7 Dead, 15 Injured After 14-Year-Old Gunman Opens Fire at Debsirin Nonthaburi School

NONTHABURI, THAILAND — A horrific violent attack unfolded on Friday, August 7, 2026, when a 14-year-old student opened fire inside Debsirin Nonthaburi School on the northwestern outskirts of Bangkok. The shooting resulted in seven fatalities at the campus—including three teachers, three students, and the teenage gunman himself, who died from a self-inflicted gunshot wound—along with at least 15 others injured.

Investigators revealed that prior to arriving at the secondary school, the suspect had fatally shot his grandparents at their family home in Bang Bua Thong district.

The shooting began around mid-morning as classes were underway for the school's estimated 3,100 students. Witnesses reported hearing dozens of gunshots ringing across the campus buildings. Authorities recovered 26 spent shell casings and found an additional 34 live rounds of ammunition in the shooter's possession.

"I didn't think it was a gun at first," an 18-year-old student recalled. "There were many shots: bang bang bang. Then it went quiet. Then it started again."

Panicked students ducked under desks and barricaded themselves inside classrooms while first responders and police units rushed to the scene. Volatile scenes unfolded along adjacent roadways as parents desperately converged near the school gates to locate their children.

Rescue teams from the Poh Teck Tung Foundation and municipal emergency services established a triage and staging center directly outside the campus. Paramedics treated victims suffering from gunshot wounds to their chests, backs, and extremities before transferring critical patients to regional hospitals.

Royal Thai Police Spokesperson Lt. Col. Trirong Phophan confirmed the shooter acted alone using a handgun believed to belong to a family member.

Prime Minister Anutin Charnvirakul expressed deep condolences to the families of the victims and announced a full inquiry into how the minor obtained the firearm, amid renewed public calls to address gun violence and security protocols across educational institutions in Thailand.

As grief washes over the local community, mental health professionals and trauma counselors have begun setting up support services for surviving students, staff, and affected families. Meanwhile, school administrators announced that classes will be suspended indefinitely to allow for ongoing forensic processing and to assess urgent security enhancements.
