Police Were Already Deployed at Bangkok’s Siam BTS—Then Two Students Were Stabbed
BANGKOK, Thailand — A clash involving vocational students at one of Bangkok’s busiest transport hubs has reignited concerns over long-running student rivalries after two students were injured in an apparent stabbing at BTS Siam station on Monday morning, September 7.
The confrontation broke out at around 8 a.m., as commuters moved through the Siam area. Police from Pathum Wan Police Station responded and deployed crime-prevention and suppression officers to control the situation and secure the area.
Despite the police presence, two students were injured in the incident.
According to reports cited by Thai media, the victims were students from Pathumwan Institute of Technology, while the opposing group was linked to Rajamangala University of Technology Tawan-ok’s Uthenthawai campus. Thai Enquirer reported that the confrontation involved roughly 30 Uthenthawai students and that the two injured students, aged 19 and 21, suffered stab wounds to the back. They were taken to hospital and were reported to be in stable condition.
Police have not publicly established the full circumstances surrounding the confrontation. Officers from Metropolitan Police Bureau Division 6 and Pathum Wan Police are reviewing CCTV footage in an effort to identify those involved and determine what led to the violence. The exact weapon used and the cause of the confrontation remain under investigation.
Clash caught the attention of commuters
A bystander reportedly recorded part of the confrontation as commuters watched the incident unfold near the station.
The incident is particularly concerning because Siam is a major interchange and commercial area in central Bangkok, meaning clashes in the area can put not only students but also commuters, shoppers and other members of the public at risk.
The latest incident also comes only days after another student brawl in the same broader Pathum Wan area.
On August 28, eight students were arrested after a fight between rival educational institutions on the OneSiam Skywalk, with four people reportedly injured, according to the Bangkok Post.
A rivalry authorities have struggled to contain
The latest stabbing is not an isolated episode.
The rivalry between students associated with Pathumwan Institute of Technology and Uthenthawai has a long history, with authorities repeatedly introducing patrols, weapon checks and other measures to prevent confrontations.
Thai police have previously described student violence in the area as a serious public-safety concern. In January 2026, officers increased surveillance around Pathum Wan and the two institutions ahead of Uthenthawai's annual anniversary, known as “Blue Day.” Police conducted patrols around high-risk areas and seized unattended knives during one operation.
The institutions themselves have also taken preventive measures.
In July, Pathumwan Institute of Technology announced restrictions on students entering its campus from July 12 to August 9, 2026, with online classes introduced as part of measures intended to prevent disturbances connected with the Uthenthawai area and the institute's anniversary period.
The tensions have been serious enough in the past to trigger government intervention. In 2024, Thailand's higher-education minister ordered Uthenthawai to stop accepting new students and accelerate plans for relocation, citing repeated clashes involving students from the two institutions.
Why the latest incident matters
The renewed violence raises a difficult question for Bangkok authorities: How can recurring student clashes be prevented when police are already being deployed in known high-risk areas?
The problem is not new. A CNA investigation into the rivalry documented decades of violence between vocational students in the Pathum Wan area and noted that authorities had previously used targeted patrols, weapon searches and agreements with the schools in an effort to prevent clashes.
Earlier incidents have also involved serious injuries and fatalities, underscoring why authorities continue to treat encounters between rival student groups as a significant security concern.
For now, investigators are focusing on CCTV footage and witness information to establish exactly what happened at Siam BTS and identify those responsible.
No final determination has been announced regarding the motive, the identities of all participants or possible charges.
The investigation remains ongoing.
