Violence flares near Bangkok’s IMF and World Bank summit as police clash with protesters trying to hang banners from a bridge. Demonstrators are injured, but Bangkok police chief Siam Boonsom denies ordering force. An overnight protest site is now agreed on.
Police clashed with anti-IMF protesters in central Bangkok on Thursday, leaving demonstrators injured as tensions flared outside the IMF–World Bank meetings. The violence broke out over banners on a pedestrian bridge. Metropolitan Police Commissioner Siam Boonsom denied ordering force, blaming police miscommunication. Yet no officers faced announced disciplinary action. Injured protesters were told to file complaints, while police negotiated an overnight protest area. No demonstrators were charged.

Bangkok’s Metropolitan Police Commissioner denied ordering violence against anti-IMF protesters on Thursday after clashes at Rama IV intersection left demonstrators injured. Police Lieutenant General Siam Boonsom blamed miscommunication for the confrontation near the Queen Sirikit National Convention Centre.
The trouble began when protesters attempted to display banners from a pedestrian overpass. However, officers and demonstrators became involved in a physical struggle. In response, the commissioner invited injured protesters to file complaints against police. Meanwhile, negotiations secured an overnight demonstration area, with no criminal charges filed against participants.
The confrontation occurred on Thursday morning, October 15, during protests against the International Monetary Fund (IMF) and World Bank meetings. Demonstrators had assembled near Rama IV intersection, close to the conference venue.
Police and protesters clash over banners as Bangkok commissioner denies orders to use violence
Police were maintaining security around the gathering while managing access to surrounding roads. However, tensions developed when protesters prepared to hang banners from a pedestrian overpass. Officers intervened, and a physical struggle followed, leaving demonstrators injured.
Metropolitan Police Commissioner Siam Boonsom subsequently visited the demonstration to supervise security arrangements and explain the confrontation. According to his account, protesters had become concerned after seeing police stationed on the pedestrian bridge. Officers therefore withdrew from the overpass to ease tensions.
However, some demonstrators then climbed onto the bridge to prepare their banners. The movements created confusion, followed by physical contact between officers and protesters.
Siam maintained that the confrontation resulted from miscommunication rather than instructions to suppress the demonstration. He insisted that senior police commanders had issued no orders to use force or violence.
Nevertheless, the incident had already resulted in injuries to protesters. The commissioner acknowledged that complaints could be filed if officers had acted excessively or broken the law. He also confirmed that police were coordinating with the National Human Rights Commission.
Police blame confusion on pedestrian bridge as injured demonstrators are told to file complaints
The police explanation centred on the sequence of events surrounding the attempted banner display. Initially, officers were positioned on the overpass as part of the security operation. Their presence caused concern among demonstrators, according to Siam.
Consequently, police withdrew from the bridge to reduce tensions. Yet protesters subsequently moved onto the same structure to prepare their banners. The commissioner said confusion developed during these movements, leading to the confrontation.
The resulting injuries raised questions about the conduct of officers involved in the struggle. However, Siam did not announce findings concerning individual police misconduct. Nor did he identify officers accused of using excessive force.
Instead, he told demonstrators they could report unlawful conduct immediately. Complaints could be submitted directly to police or referred to the National Human Rights Commission. The commission was already observing the demonstration and maintaining contact with officers.
Injured protesters offered complaint channels as police deploy medical teams and volunteers at rally
The commissioner specifically addressed incidents involving excessive police action resulting in injuries. Protesters who believed officers had broken the law could lodge formal complaints without delay. Furthermore, the National Human Rights Commission offered another channel for reporting the confrontation.
Siam confirmed that police had coordinated with its representatives during Thursday’s operation. Nevertheless, his statement did not establish how many demonstrators had been injured or the severity of their injuries.
Separately, the Metropolitan Police Commissioner arranged medical assistance for participants attending the demonstration. A team from the Police Hospital was brought to Rama IV intersection.
Volunteers also assisted protesters, many of whom were elderly. In addition, police supplied drinking water to those gathered near the conference venue. These measures accompanied the continuing security deployment following the morning confrontation.
The medical team formed part of the police arrangements for the public assembly. However, Siam did not specify whether protesters injured during the struggle required hospital treatment. Neither did his statement provide individual casualty details.
Instead, the commissioner concentrated on the police explanation and the procedures available for reporting misconduct. He reiterated that officers had received no orders to use violence against demonstrators.
Security around IMF and World Bank meetings comes under scrutiny after confrontation on overpass
The incident occurred during heightened security surrounding the IMF and World Bank meetings in Bangkok. Police were responsible for protecting the international gathering while managing demonstrations near the Queen Sirikit National Convention Centre.
Consequently, officers were stationed around Rama IV intersection and surrounding access routes. The pedestrian overpass became a focal point when protesters attempted to display their banners. The subsequent confrontation brought officers and demonstrators into direct physical contact.
The police account described the confrontation as an unintended consequence of confusion on the bridge. Officers had initially occupied the overpass before withdrawing in response to protesters’ concerns.
Subsequently, demonstrators approached the banner position, creating further uncertainty over movements in the area. Siam said the resulting struggle had not been authorised by senior commanders. However, the explanation did not establish responsibility for the injuries sustained during the incident.
Notably, the commissioner distinguished between police orders and the conduct of individual officers. He maintained that no instruction to use violence had been issued.
Nevertheless, protesters could pursue complaints if they believed officers had exceeded their powers. Such complaints could concern excessive force, unlawful conduct or injuries resulting from police actions. The National Human Rights Commission remained available to receive complaints while observing developments at the protest site.
Police negotiate overnight protest area near Rama IV intersection while keeping conference roads clear
Meanwhile, police faced another immediate issue as demonstrators prepared to remain near Rama IV intersection overnight. Officers therefore negotiated arrangements with protest representatives.
The discussions produced an agreement identifying a designated gathering area. According to Siam, the location was intended to prevent disruption to surrounding traffic. It was also intended to maintain security measures connected with the international conference.
The commissioner confirmed that the overnight gathering area had been clearly defined following negotiations. Police sought to keep roads accessible while maintaining their security operation around the conference venue.
However, Siam did not announce a prohibition on the overnight demonstration. Instead, officers continued coordinating with protest representatives over the arrangements. The agreement followed the morning confrontation and formed part of efforts to manage the continuing assembly.
In parallel, police maintained their responsibilities for traffic control and conference security. The presence of demonstrators near Rama IV intersection required arrangements covering both activities. Consequently, officers negotiated a specific location where protesters could remain without obstructing surrounding roads.
Siam said the gathering area had been established through discussions with participants. The arrangements allowed the police operation to continue while demonstrators remained near the venue.
No charges filed against demonstrators as police decline to announce findings on officers’ conduct
Significantly, the Metropolitan Police Commissioner confirmed that no criminal charges had been filed against protesters at that stage. The announcement followed the physical confrontation involving officers and demonstrators earlier that morning.
However, police had not announced prosecutions arising from the incident. Nor had they reported criminal proceedings connected with the attempted banner display. Instead, officers continued managing the demonstration through negotiations and security arrangements.
The absence of charges against demonstrators did not resolve the circumstances surrounding the injuries. Siam maintained that protesters could immediately report police misconduct if they believed officers had acted unlawfully.
Furthermore, he specifically referred to complaints involving excessive force and injuries. The National Human Rights Commission was observing the gathering and coordinating with police. Nevertheless, the commissioner announced no findings concerning responsibility for the confrontation.
The police statement also contained no announcement of disciplinary proceedings against officers involved in the incident. Similarly, Siam did not identify any police personnel accused of misconduct.
His explanation concentrated on the movements of officers and protesters before the struggle. According to the commissioner, police withdrew from the overpass to ease concerns. However, confusion followed when demonstrators subsequently approached the banner position.
Bangkok police maintain conference security and medical support after clashes with anti-IMF protesters
The confrontation occurred as police maintained security around one of Bangkok’s major international financial gatherings. Demonstrators were protesting against the IMF and World Bank meetings near the conference venue.
Officers were simultaneously managing security, traffic and the public assembly. However, the dispute over the pedestrian overpass brought those responsibilities into direct conflict. The resulting injuries prompted the commissioner to address police conduct publicly.
As part of the continuing operation, Siam personally supervised arrangements at Rama IV intersection. He also brought medical personnel, volunteers and drinking water to assist demonstrators. Meanwhile, officers negotiated the overnight gathering area and coordinated with the National Human Rights Commission.
These measures followed the morning confrontation, although they did not alter the commissioner’s explanation. He maintained that the struggle resulted from miscommunication rather than orders to use violence.
The commissioner also made clear that protesters retained access to formal complaint procedures. Those alleging excessive police force could submit reports directly to police.
Alternatively, they could approach the National Human Rights Commission. The commission’s presence provided an additional channel for complaints concerning Thursday’s events. However, Siam did not confirm whether any formal complaints had already been lodged.
Injury figures and responsibility remain unresolved as police insist no orders for violence were issued
The police account therefore left several factual questions unresolved. It did not establish the precise number of injured protesters or describe their injuries. Neither did it identify individual officers responsible for any unlawful conduct. Moreover, no disciplinary action against police personnel was announced. The commissioner instead reiterated that allegations could be pursued through established complaint procedures.
By Thursday, police had confirmed that the confrontation followed confusion over movements on the pedestrian bridge. Siam denied that commanders had ordered officers to use violence.
Meanwhile, no criminal charges had been filed against demonstrators. Police had also negotiated arrangements for the overnight gathering, with traffic management and conference security remaining priorities.

The Metropolitan Police Bureau continued overseeing the demonstration near Rama IV intersection following the morning clashes. Officers remained responsible for securing the IMF and World Bank meetings while managing the public assembly.
In addition, medical personnel and volunteers were available to assist protesters. The National Human Rights Commission continued observing developments, while police maintained contact with its representatives.
Ultimately, Siam’s explanation placed the cause of Thursday’s confrontation on miscommunication between officers and demonstrators. However, it did not determine responsibility for the injuries sustained during the struggle. Protesters were invited to file complaints over excessive or unlawful police conduct. Meanwhile, the overnight demonstration arrangements remained in place, and no charges against participants had been announced.
