A Thai eighth-grade student killed five people and himself at Debsirin Nonthaburi School on the northwestern outskirts of Bangkok on Aug 7, 2026, using a grandfather’s gun, according to police statements reported by Reuters.

School Shooting Details and Casualties at Debsirin Nonthaburi School

The 14-year-old student fired at least 26 bullets during the Aug 7 incident, according to National Police figures reported by Reuters. Police later found 34 additional unspent rounds at the scene. Education Minister Prasert Jantararuangtong confirmed to Reuters that the dead included both teachers and students. Emergency personnel responding to the scene discovered a male teacher dead on an upper floor, while emergency worker Kiatikhun Verapongpradith described treating students with injuries to their backs, chests, and arms.

Trirong Phophan, a spokesman for the National Police, told Reuters that 15 people sustained injuries during the active phase of the attack. Prime Minister Anutin Charnvirakul later stated that nine of the wounded remained in critical condition following hospital transport. The school enrolled approximately 3,100 students alongside 147 teachers during the 2025 academic year, district authorities reported.

Prior Investigation into Grandparents Uncovers Earlier Deaths

Police discovered the bodies of the teenager’s grandparents at their home after investigating the origin of the firearm used in the school attack. Prime Minister Anutin Charnvirakul told reporters after official consultations that the gunman lived with his grandparents and had suffered from stress related to his studies. The weapon utilized in the classroom shooting belonged to the grandfather, according to law enforcement officials.

Gun Control Measures and Historical Context of Violence in Thailand

The Aug 7 shooting is the second school-related fatal incident in Thailand in 2026, following a February attack in the southern city of Hat Yai where a teacher died and a student sustained injuries. Prime Minister Anutin Charnvirakul vowed to introduce a new firearms control law in response to the latest violence. Following a 2023 shopping center shooting involving a 14-year-old perpetrator, Anutin—then serving as interior minister—enacted short-term licensing bans, import restrictions, and age limits at shooting ranges alongside mandatory mental health evaluations for gun owners.

Thailand’s most lethal mass killing by a single perpetrator occurred in 2022, when a former policeman killed 36 people in a gun-and-knife attack in the country’s northeast, including 22 children at a daycare center. Additional high-profile incidents include a 2020 military rampage in Nakhon Ratchasima that left 29 dead, and a July 2025 market shooting in Bangkok where a gunman killed five people before taking his own life.
