Police swoop on Chinese tourist, 51, at Don Mueang on Sunday, October 11, over two earlier flight thefts. Cards and cash worth ฿317,662 vanished on October 5 and 7. Payments surfaced in China. Now detectives probe 37 airport journeys and possible accomplices.
A Chinese man was arrested at Bangkok’s Don Mueang Airport on Sunday, October 11, over two suspected mid-air thefts on earlier domestic flights. The first occurred on October 5, aboard a flight from Chiang Rai. The second followed on October 7, from Chiang Mai. Both passengers reported credit cards stolen from overhead luggage, followed by fraudulent payments in Heyuan, China. Total losses reached ฿317,662, including ฿25,000 in stolen cash. Police identified Zheng Yu Qlang, 51, aboard both flights and arrested him after another journey from Chiang Rai. Investigators uncovered 37 recorded journeys through Bangkok’s airports, suspicious Chinese payment transfers and online gambling links. Police are now hunting possible accomplices and probing how the stolen cards were used in China so quickly. Zheng still denies wrongdoing despite the evidence against him.

A Chinese tourist was arrested at Bangkok’s Don Mueang Airport on Sunday over suspected in-flight thefts involving nearly ฿293,000 in credit card fraud.
Police intercepted the 51-year-old after his flight from Chiang Rai, following complaints from two passengers. Both victims discovered missing valuables and unauthorised payments linked to the same city in China.
More significantly, investigators uncovered 37 recorded journeys through Bangkok’s main airports and suspicious financial transfers through Chinese payment platforms. Police are now hunting possible accomplices in a suspected international theft operation targeting passengers’ overhead luggage.
Chinese suspect arrested at Don Mueang after police link him to two flights and stolen credit cards
The suspect, identified as Zheng Yu Qlang, 51, was arrested on October 11 after arriving from Chiang Rai. Officers intercepted him at the domestic arrivals terminal under a Criminal Court warrant.
The arrest followed two complaints involving separate domestic flights earlier this month. Both passengers reported missing credit cards and unauthorised transactions traced to Heyuan, Guangdong province, China.
Crucially, investigators established that Zheng had travelled aboard both aircraft. Witness accounts and airline passenger records subsequently became central to the case. The Chinese national faces charges of theft at an airport and unauthorised use of another person’s electronic card. However, he denies involvement in either incident.
Meanwhile, police are examining whether the suspect worked with accomplices handling stolen card transactions. Investigators are also reviewing his extensive travel history and financial transfers through Chinese payment platforms. The arrest operation involved Don Mueang Police Station investigators, airport personnel and officers from other police units.
Senior Bangkok police investigate first flight theft as passenger loses ฿265,067 to transactions in China
The investigation was led by senior officers from Metropolitan Police Division 2 and Don Mueang Police Station. They included Police Major General Tanongsap Maneechot, Commander of Metropolitan Police Division 2. Police Colonel Natthapol Komintrachart, Deputy Commander, also participated. In addition, Police Colonel Wanchai Wongwanichanan, Superintendent of Don Mueang Police Station, oversaw the local investigation.
Police Lieutenant Colonel Amnat Chamchaem, Deputy Superintendent of Investigation, subsequently disclosed details of the evidence. Police Lieutenant Colonel Pakin Dokmai, Chief Investigator at Don Mueang Police Station, was also involved.
Together, the officers coordinated enquiries involving airline records, witness accounts and the suspect’s movements through Thailand.
The case began with a passenger travelling from Chiang Rai to Don Mueang on October 5. Shortly after landing in Bangkok, the traveller received a bank notification concerning an unsuccessful credit card transaction. The attempted payment involved 4,000 yuan, equivalent to approximately ฿20,000. Notably, the transaction originated in Heyuan, Guangdong province, China.
However, a subsequent check of the passenger’s banking application revealed a far greater loss. Three earlier transactions had already been completed successfully. Together, they totalled HK$62,000, equivalent to approximately ฿265,067. The passenger had not authorised any of the payments.
Second passenger loses cash and credit card as witness spots suspicious activity aboard Chiang Mai flight
The missing card had been stored inside a bag in the aircraft’s overhead compartment. Consequently, the passenger suspected someone had searched the luggage during the flight. A complaint was then filed with police at Don Mueang Airport. Investigators began examining the missing card, the timing of the payments and their connection to China.
Two days later, on October 7, another passenger reported a strikingly similar incident after arriving from Chiang Mai. This time, the victim discovered ฿25,000 in cash and a credit card missing from a shoulder bag. The bag had been placed inside an overhead compartment above the passenger seats.
Significantly, the passenger’s friend had noticed a man apparently searching through luggage in the same compartment. The witness described the individual as appearing to be Chinese. Moreover, the friend reportedly recorded the man’s suspicious behaviour. This provided investigators with additional evidence concerning the movements of a possible offender.
After landing, the second victim received four notifications concerning credit card transactions. Two attempted payments were unsuccessful. However, two others went through, resulting in unauthorised charges totalling approximately ฿27,595. The successful transactions involved 5,500 yuan and were traced to Heyuan, Guangdong province.
Matching payments in China led police to identify suspect aboard both flights and secure arrest warrant
Remarkably, this was the same Chinese city identified in the first complaint. The passenger confirmed that none of the payments had been authorised.
Including the missing cash, the second victim’s reported losses reached approximately ฿52,595. Police now had two complaints involving overhead luggage and unauthorised payments linked to the same location.
Investigators compared the incidents and examined whether the same offender was responsible. Police Lieutenant Colonel Amnat said the similarities pointed towards a common perpetrator. Both flights arrived at Don Mueang, and both passengers reported valuables missing from overhead compartments. Furthermore, the unauthorised card transactions were linked to Heyuan shortly after arrival.
Police therefore reviewed passenger manifests and other available airline records. Their enquiries established that Zheng had travelled aboard both aircraft. Witnesses also identified the Chinese national in connection with the suspected thefts. The investigation subsequently moved towards securing his arrest.
Officers coordinated with Chiang Mai Tourist Police and officials at Chiang Rai Airport to verify Zheng’s identity. They then assembled evidence and obtained an arrest warrant from the Criminal Court. Meanwhile, investigators received information about another journey the suspect was planning.
Police intercept Chinese suspect arriving from Chiang Rai and seize cards, phones and foreign currency
Zheng was scheduled to travel from Mae Fah Luang Airport in Chiang Rai to Bangkok on October 11. His flight was due to reach Don Mueang at approximately 2.50 pm. In response, investigators coordinated with airport officials to intercept him following his arrival.
Officers waited at the domestic arrivals terminal as passengers disembarked. Zheng was intercepted while leaving the connecting walkway. The arrest was recorded at approximately 4 pm on Sunday, October 11. Police then searched the suspect and seized several items for further examination.
The recovered property included credit cards, two mobile telephones and ฿35,950 in Thai currency. Officers also found banknotes from 12 foreign countries. Additionally, they seized a black shoulder bag, a black jacket and a baseball cap. The items were taken into police custody as part of the criminal investigation.
Zheng was subsequently transferred to Don Mueang Police Station for questioning. During his initial interview, he denied stealing money or credit cards from airline passengers. He claimed to have entered Thailand alone on October 3 as a tourist. Furthermore, he told officers that he had been staying at a hotel in Bangkok’s Huai Khwang district.
Despite his denial, investigators continued examining evidence linking him to the two flights and reported losses. Police Lieutenant Colonel Amnat also outlined the suspected methods used by criminals targeting passengers aboard domestic aircraft. His account described organised movements inside aircraft cabins and the targeting of overhead luggage.
Police describe how in-flight thieves search overhead luggage while passengers rest after take-off
According to the officer, individuals involved in these operations purchase airline tickets and travel alone. They generally avoid speaking to other passengers or interacting with people while waiting at airports. Once aboard, they remain alert for opportunities to search luggage. Their movements are timed to coincide with passengers settling down during the flight.
The officer said suspects typically begin moving around the cabin approximately 30 minutes after take-off. By then, many passengers have settled into their seats and begun resting. The suspects subsequently approach overhead compartments containing passengers’ hand luggage. They pretend to retrieve their own belongings while searching bags belonging to other travellers.
Police say the method allows offenders to examine several compartments without immediately attracting attention. They particularly target bags containing cash, credit cards and other valuables. In some cases, suspects reportedly search almost every compartment near their seats. Meanwhile, passengers may remain unaware that their belongings have been opened.
The suspected operation does not end when the aircraft lands. Police said stolen credit cards are subsequently used to purchase goods in China. In some cases, these transactions occur shortly after the aircraft arrives. This timing became a central feature of the investigation into the two Don Mueang complaints.
Police probe rapid Chinese card payments and suspect’s 37 recorded journeys through Bangkok airports
Both victims discovered unauthorised payments connected to Heyuan, Guangdong province. Moreover, the payments were recorded around the time their flights arrived in Bangkok. Investigators are therefore examining how the stolen cards could have been used so quickly. One possibility under investigation involves portable credit card payment equipment.
However, police have not confirmed that such equipment was used in either incident. Nor have investigators reported recovering a portable payment terminal during Zheng’s arrest. The precise method used to process the unauthorised transactions remains under examination. Officers are also investigating whether other individuals participated in handling the payments.
On another front, investigators uncovered an extensive history of travel through Thailand’s principal international airports. Checks revealed that Zheng had made 37 recorded journeys through Don Mueang and Suvarnabhumi airports. According to Police Lieutenant Colonel Amnat, the records extended from late 2014 until the present. Investigators also identified two journeys involving Chiang Rai Airport.
The travel records have become another focus of the investigation. Officers are examining the movements alongside the two domestic flights identified in the complaints. Nevertheless, police have not established that thefts occurred during the other recorded journeys. No additional victims connected to those flights have been confirmed.
WeChat and Alipay transfers reveal payments to associates and transactions linked to online gambling
Separately, financial investigators examined transactions associated with Zheng. Their enquiries uncovered payments involving WeChat and Alipay, two widely used Chinese electronic payment platforms. Police identified transfers from merchants to the suspect through these services. Some funds were subsequently forwarded to other individuals.
Police Lieutenant Colonel Amnat said recipients included friends and women. Notably, some payments were made through electronic red-envelope functions, commonly described as ang pao transfers. These services allow users to send money electronically to other individuals. Investigators also discovered transactions connected to online gambling.
The financial records are now being examined to establish the purpose of the transfers. Police are also investigating whether the transactions were connected to the suspected thefts. However, officers have not disclosed the total value of payments identified through WeChat and Alipay. They have also not confirmed that every transfer involved proceeds from stolen credit cards.
The financial enquiries are continuing alongside investigations into the unauthorised purchases in China. Officers are seeking to establish whether other individuals received money connected to the suspected operation. In parallel, investigators are examining the relationship between merchant payments, electronic transfers and the suspect’s recorded movements.
Searches for card readers add to investigation of suspected air rats targeting luggage aboard aircraft
Police also reviewed Zheng’s social media activity. According to Police Lieutenant Colonel Amnat, investigators discovered searches concerning credit card readers.
This finding has become relevant to enquiries into the speed of the unauthorised transactions. Officers are examining whether electronic payment equipment could explain how purchases were processed shortly after landing.
However, investigators have not disclosed technical evidence establishing how the payments were completed. They have also not confirmed recovering equipment capable of processing the stolen cards. Consequently, the financial transactions, electronic records and possible involvement of accomplices remain under investigation.
The suspected offences have been linked to a form of in-flight theft commonly associated with criminals known as air rats. The term describes offenders who board passenger aircraft specifically to steal valuables from hand luggage. In this case, police believe the suspects targeted bags stored in overhead compartments.
The method described by investigators involves waiting until passengers are resting or distracted. Offenders then approach luggage compartments while pretending to retrieve their own belongings.
Two passengers report ฿317,662 in combined losses as police examine seized cards and mobile phones
According to police, they may search several bags during a single flight. The two Don Mueang complaints contained similar accounts of missing valuables and unauthorised payments.
The first victim reported three successful credit card transactions worth approximately ฿265,067. The second reported two successful payments totalling approximately ฿27,595. Together, the unauthorised card transactions amounted to approximately ฿292,662. Including the missing ฿25,000 in cash, the two victims reported combined losses of approximately ฿317,662.
Both passengers also received notifications concerning unsuccessful payment attempts. The first reported an attempted transaction worth approximately ฿20,000. The second reported two unsuccessful payments, although their individual values were not disclosed. Accordingly, these attempted transactions were excluded from the reported financial losses.
Police have not announced whether the stolen cash or money charged to the cards has been recovered. They have also not confirmed whether any seized credit cards belonged to the two complainants. The recovered cards remain part of the investigation. Similarly, the two seized mobile telephones are available for further examination.
Police pursue possible accomplices as Guangdong transactions and flight records remain under scrutiny
Investigators are pursuing enquiries into financial transfers, communications and possible additional participants. The suspect’s movements between Bangkok, Chiang Rai and Chiang Mai are also being reviewed. Although the two domestic flights remain central to the case, police are examining whether other passengers suffered similar losses.
The transactions traced to Guangdong have become another important element of the financial investigation. Both sets of successful payments were linked to the same Chinese city. Their timing has also attracted police attention. Investigators are examining whether the cards were used through equipment or arrangements involving other individuals.

For now, police have not established the identities of any accomplices. No additional arrests have been announced in connection with the suspected operation. Police Lieutenant Colonel Amnat said further enquiries would seek to identify other members of the suspected criminal network.
The investigation now covers airline records, witness accounts, financial transactions and electronic evidence. Officers are also examining the relationship between stolen credit cards and payments made through Chinese platforms. The Criminal Court warrant provided the basis for Zheng’s arrest at Don Mueang Airport on October 11.
The Chinese national continues to deny involvement in the reported thefts. Meanwhile, investigators are pursuing possible accomplices and additional offences linked to the suspected operation. The case remains under investigation at Don Mueang Police Station.
