Terrifying scenes in Bangkok as a motorcyclist, 19, chases a woman after a horn warning, smashes her windscreen and punches her. Bystanders fail to help. He pleads guilty in court, while fresh questions again mount over previous attacks and drug use.
A 19-year-old motorcyclist has been sent to Bangkok Remand Prison after a brutal road rage attack on a woman driver. Natthanon, nicknamed Leng, smashed her windscreen and punched her near the eye after she sounded her horn at a busy Bangkok intersection. Despite her apologies, the violence continued as bystanders failed to intervene. Arrested on Friday, he pleaded guilty to assault and criminal damage on Saturday. However, he insists he did not know his victim was female. Meanwhile, reports of previous attacks on women motorists have surfaced, alongside an unresolved drug accusation. The case follows further violent road confrontations across Thailand. Police have also announced tougher traffic enforcement priorities, while aggressive horn use can attract fines of ฿2,000. Sentencing is scheduled for 15 December.
A 19-year-old motorcyclist who punched a woman driver and smashed her car windscreen in Bangkok has been remanded in custody. The vicious road rage attack followed a dispute over a car horn at a busy intersection on Thursday evening.
Video footage spread across social media, triggering nationwide outrage. Police arrested the suspect on Friday before bringing him to court on Saturday. He pleaded guilty to assault and criminal damage. However, he denied accusations linking him to previous attacks on female motorists.
Separately, questions remain over a drug-use accusation raised by police. The case comes amid fresh warnings about aggressive horn use and a Royal Thai Police drive to improve traffic discipline.
Bangkok motorcyclist follows woman after horn honking before smashing her windscreen in heavy traffic
The suspect, identified as Natthanon, 19, and nicknamed Leng, appeared before the Phra Nakhon Nuea District Court on Saturday, 24 October. His appearance followed a violent confrontation with a 27-year-old woman near Bangkok’s Lat Phrao Five-Way Intersection.
The incident occurred at approximately 7.50 pm on Thursday, 22 October. The victim, identified in Thai reports as Ms Princhanom, was driving a Honda Jazz near Union Mall.
According to her account, the motorcyclist suddenly braked after passing a designated U-turn point. She briefly sounded her horn to warn him of a possible collision. However, the warning apparently angered the rider. He subsequently followed her vehicle as she continued towards Chatuchak Park. Heavy traffic slowed the Honda Jazz, allowing the motorcyclist to catch up.
The rider approached the driver’s side and began shouting abuse. He pulled at the door, struck the side window and demanded that the woman get out. The confrontation then took a violent turn. Natthanon climbed onto the bonnet and repeatedly stamped on the windscreen. The glass cracked under his blows as the woman remained trapped inside.

Fearing for her safety, the driver initially refused to leave the vehicle. Instead, she raised her hands in a traditional Thai wai, attempting to apologise.
However, the motorcyclist continued his attack. Eventually, she opened the driver’s door and attempted to calm him. What followed was a direct physical assault. Natthanon punched her in the face, striking the area around her left eye.
The blow caused bruising and bleeding around her eye socket. Afterwards, the motorcyclist walked away from the scene. The woman was left injured beside her damaged Honda Jazz. Notably, she told reporters that nobody nearby had intervened during the confrontation. The attack unfolded in heavy traffic at one of Bangkok’s busiest intersections. Yet, according to her account, no bystander came to her assistance.
The victim subsequently reported the attack to Phahon Yothin Police Station. Video footage of the confrontation circulated rapidly online, attracting widespread public anger. The images showed the motorcyclist attacking the woman’s vehicle during the dispute. As the footage spread, investigators worked to identify the rider. Police eventually established that he was Natthanon, aged 19.
Arrested rider claims woman struck his motorcycle and insists he did not know the driver was female
Officers brought the suspect to Phahon Yothin Police Station for questioning on Friday evening. The arrest came approximately one day after the assault. Meanwhile, the victim thanked police, journalists and social media users for helping secure his arrest.
She also confirmed that investigators had informed her of the development. Nevertheless, the suspect immediately disputed important elements of her account.
Natthanon claimed the woman’s Honda Jazz had struck or grazed his motorcycle before the confrontation. He maintained that she had failed to stop and discuss the collision. His explanation differed from the woman’s account of briefly sounding her horn. Furthermore, he claimed that he had not realised the driver was female when he attacked her. He also insisted that he had not noticed her apologetic gesture.
The victim firmly rejected that explanation. She maintained that she had opened the car door and raised her hands in a wai before being punched. Consequently, she disputed his claim that he could not have known she was a woman. Her account placed the apology before the assault, not afterwards. The suspect nevertheless maintained his explanation during questioning.
Police question suspect over earlier attacks on female motorists and separate accusations of drug use
Pressed by reporters, Natthanon acknowledged wrongdoing and apologised for his actions. However, he declined to explain his motive when questioned about the violence. He also faced questions concerning accusations that he had previously attacked other motorists. Those questions followed Thai media reports of earlier incidents involving female drivers and damaged vehicles.
According to Thairath, two women had previously reported attacks involving stones thrown at their cars. Both incidents reportedly followed disputes concerning the sounding of vehicle horns. The complaints were associated with the Taling Chan and Bang Pho police jurisdictions. As a result, fresh questions emerged about whether Natthanon had previously been involved in similar confrontations.
However, the available reports have not established convictions connecting him to those incidents. The suspect specifically denied committing similar acts of violence within the Bang Pho police jurisdiction. Police also questioned him about accusations concerning drug use. He declined to answer reporters on that issue. Subsequently, the drug accusation appeared in reports concerning his appearance before the district court.
By Saturday morning, investigators had completed the initial procedures required to bring Natthanon before a judge. Officers escorted him from Phahon Yothin Police Station to the Phra Nakhon Nuea District Court. He arrived for proceedings at approximately 11 am. Police had referred to assault, property damage and drug use when presenting the accusations. However, the prosecutor’s reported formal case concerned assault and criminal damage.
Court hears guilty plea to assault and criminal damage before sending 19-year-old to Bangkok prison
The assault charge was brought under Section 295 of Thailand’s Criminal Code. This provision concerns causing physical or mental harm to another person. In addition, prosecutors pursued criminal damage under Section 358. That provision covers the destruction or damage of property belonging to another person. The second charge concerned the attack on the woman’s Honda Jazz and its windscreen.
Natthanon pleaded guilty to the offences presented by prosecutors. The court then ordered an investigation into his background before determining his sentence. Probation officers were instructed to prepare an assessment within 15 days. Meanwhile, police opposed his release on bail. The suspect did not submit an application seeking temporary release. He was subsequently transferred to Bangkok Remand Prison.
The court scheduled its verdict and civil mediation proceedings for 15 December 2026 at 9.30 am. Accordingly, the guilty plea has not yet resulted in a final sentence. The judge must first consider the probation assessment. The civil proceedings also remain outstanding. Meanwhile, the woman has indicated that she intends to pursue the case despite the suspect’s apology.
She said an apology alone was insufficient following the attack and damage to her vehicle. Her position followed the suspect’s admission of wrongdoing during questioning. Nevertheless, the two accounts of the original traffic dispute remain different. Natthanon maintains that her vehicle struck his motorcycle. The woman insists that she briefly sounded her horn to warn him after he suddenly braked.
Drug accusation being reviewed as separate road rage confrontations emerge in Sukhothai and Bangkok
The separate drug-use accusation also remains unresolved in the published court account. Although police raised the issue, the reported prosecutor’s case concerned assault and criminal damage. No confirmed report establishes whether the suspect tested positive for drugs. Equally, the available information does not establish whether prosecutors intend to pursue separate proceedings.
The Bangkok assault follows another violent confrontation involving motorists earlier this month. On 17 October, police in Si Samrong district, Sukhothai province, investigated a dispute involving two women. One was driving a white car. The other was riding a motorcycle with a child passenger. Video footage subsequently showed the car cutting across the motorcycle’s path before a physical confrontation followed.
The Sukhothai footage also circulated online, attracting criticism because a child was present during the incident. Police later confirmed that the two women had been involved in previous disputes. Investigators began collecting evidence and examining the circumstances of the confrontation. At the same time, officers were awaiting medical findings concerning injuries suffered during the incident.
The Sukhothai confrontation occurred just five days before the attack at Lat Phrao. Both incidents involved motorists becoming involved in physical confrontations following road disputes. However, the circumstances differed, and police investigated them separately. Another confrontation involving aggressive horn use had already attracted official attention in Bangkok earlier this year.
On 23 February, a motorcyclist stopped outside Lumpini Park to allow pedestrians to cross the road. A bus driver travelling behind him repeatedly sounded his horn. The situation subsequently developed into an angry confrontation between the two road users. Following reports of the dispute, the Department of Land Transport intervened. Officials ordered the bus operator to explain the incident and considered further legal action.
Police accident figures reveal thousands of deaths but provide no national measure of road rage attacks
The February incident centred on a motorcyclist stopping for pedestrians and a bus driver repeatedly sounding his horn. By comparison, the Lat Phrao assault followed a woman’s brief horn warning after another motorist suddenly braked. The Sukhothai case involved a car and motorcycle, with a child travelling as a passenger. Each incident developed under different circumstances, although all involved confrontations between road users.
Thailand also continues to record substantial numbers of road accidents, injuries and deaths. According to the National Statistical Office’s 2025 yearbook, police recorded 57,057 road accidents nationwide during 2024. Those incidents included 5,480 reported deaths. The figures were compiled using Royal Thai Police records and form part of the country’s official road accident statistics.
However, the published figures do not specifically measure road rage. They do not establish how many accidents involved threats, assaults or confrontations between motorists. Nor do they provide a comparable annual record of violent disputes between drivers. Therefore, the figures cannot establish whether road rage incidents are increasing nationally. The latest criminal cases nevertheless show the consequences of individual confrontations on public roads.
Royal Thai Police announces new traffic enforcement priorities as attention turns to aggressive horn use
Against this background, the Royal Thai Police recently announced new traffic enforcement priorities. On 17 October, Police Major General Worawit Yanjinda outlined the force’s objectives for fiscal year 2027. The deputy police spokesman addressed road discipline, accident prevention and the conduct of traffic officers. The announcement also covered transparency and accountability in traffic enforcement.
Police were instructed to improve road safety while maintaining professional standards when dealing with motorists. In particular, traffic officers were directed to behave politely and avoid concealed roadside enforcement. The guidance emphasised visible and accountable policing. Additionally, the Royal Thai Police identified accident reduction and the protection of public safety and property as priorities.
The announcement formed part of broader traffic enforcement policy rather than a specific response to road rage. Nevertheless, aggressive behaviour involving vehicle horns has received separate attention following recent confrontations. On Sunday, 25 October, Thairath published a report explaining Thailand’s restrictions on unnecessary horn use. The report cited the Traffic Accident Prevention Support Program and existing provisions of the Land Traffic Act.
Under Section 14 of the legislation, motorists may sound their horns when necessary. This includes warning another road user of a possible collision or immediate danger. However, repeatedly sounding a horn to pressure another driver can constitute a traffic offence. Prolonged honking intended to express anger or demand that another vehicle move can also breach traffic regulations.
Thai traffic law allows warning horns but provides fines of up to ฿2,000 for unnecessary use on roads
Section 148 provides for fines of up to ฿2,000 for relevant violations. The distinction concerns the purpose and circumstances of horn use. A brief warning intended to prevent a collision differs from repeated honking used to pressure another motorist. The Sunday report explained existing legislation rather than announcing a confirmed new directive from Royal Thai Police headquarters.
That distinction is relevant to the Lat Phrao assault. The woman maintains that she sounded her horn briefly after the motorcyclist suddenly braked. According to her account, the warning was intended to prevent a collision. She did not describe repeatedly honking to force him to move or express anger. By contrast, Natthanon claimed that her vehicle had already struck his motorcycle.
The competing explanations concern the events immediately preceding the confrontation. However, the subsequent violence and property damage formed the basis of the criminal proceedings. The defendant has now pleaded guilty to those offences. His explanation concerning the original traffic dispute does not change the fact of that plea.
Separately, Thailand’s police emergency service continues to receive reports of threats and violent incidents through telephone number 191. Callers are asked to provide their location, details of the incident and descriptions of those involved. Dashcam recordings and other video evidence can also assist investigators. In the Lat Phrao case, footage circulated widely before the suspect was brought before the court.
Bangkok road rage victim pursues court case as questions remain over earlier attacks and drug accusation
The victim subsequently acknowledged the assistance of journalists and social media users in securing attention for her complaint. Police arrested Natthanon on Friday evening and brought him before a judge the following morning. By Saturday, the 19-year-old had admitted assault and criminal damage. He was then transferred to Bangkok Remand Prison after making no application for bail.
The proceedings have also left several matters unresolved. Reports concerning earlier attacks on female motorists have not established convictions linking Natthanon to those incidents. He has denied previous violence within the Bang Pho police jurisdiction. Similarly, the published court account does not establish a positive drug test or separate prosecution over drug use.

For the victim, the criminal case now moves towards sentencing and civil mediation. She has maintained her intention to pursue the proceedings despite the suspect’s apology. Meanwhile, probation officers must complete the background assessment ordered by the court within 15 days. The Phra Nakhon Nuea District Court is scheduled to deliver its verdict on 15 December at 9.30 am. Civil mediation is also scheduled for that hearing.
