NONTHABURI, Thailand — A morning of classes descended into horror on Friday, August 7, 2026, when a 14-year-old ninth-grade student killed eight people—including his two grandparents and five school staff members—in a calculated shooting spree spanning his family home and Debsirin Nonthaburi School on the northwestern outskirts of Bangkok. According to law enforcement officials, the suspect first fatally shot his grandparents at their residential property in Bang Bua Thong district using his grandfather’s legally registered 9mm semi-automatic handgun. Dressed in his school physical education uniform, the teenager then traveled to the co-educational state campus, where he opened fire across multiple floors of a classroom building. The attack wounded more than 20 students and staff before ending when the shooter took his own life. Thai officials indicated that the attack appeared well-planned and motivated in part by severe academic stress.

Video Captures Corridor Panic and Calculated Attack
Grainy CCTV security footage retrieved from inside the school building captured the terrifying sequence as the gunman navigated third-floor corridors. Wearing a purple physical education shirt and carrying a black cross-body bag, the 14-year-old walked through hallway passages discharging accurate shots into classrooms and administrative offices. The footage shows chaotic scenes of panicked students and faculty scattering in all directions—running, ducking behind structural pillars, and diving into open doorways as gunshots reverberated through the complex.
Investigators determined that the suspect fired at least 26 rounds during the campus rampage, targeting specific faculty areas including the Thai language teachers' lounge and student affairs offices. When tactical teams cordoned off the building, officers recovered an additional 34 unspent rounds of ammunition from his person.
In a statement following an emergency inspection of the campus, Prime Minister Anutin Charnvirakul confirmed details regarding the suspect's background and emotional state prior to the violence.
"This is horrible; it shouldn't have happened," Prime Minister Anutin Charnvirakul stated to reporters at the scene. "The suspect was under stress and appeared to have planned the assault in advance."
Police forensic teams examining the suspect’s home computer confirmed that he had downloaded video archives of historical international mass shootings approximately one week before carrying out the tragedy.
Eyewitnesses Describe Classroom Lockdowns and Escapes
The shooting shattered what began as a routine academic morning at the prestigious college-preparatory institution, which serves roughly 3,000 students aged 12 to 18. Eyewitnesses recounted moments of intense confusion as gunshots initially sounded like bursting fireworks before faculty members realized an active shooter was moving between floors.
Prompong Namwong, an English teacher at Debsirin Nonthaburi School, recalled the harrowing experience when a terrified student rushed into his room attempting to find refuge.
"In the corridor, I heard other teachers shouting that there had been a mass shooting downstairs," Prompong Namwong said. "At that moment, I thought I was going to die, for sure."
Local business owners outside the school perimeter observed fleeing teenagers spilling onto nearby streets as emergency vehicles swarmed the area.
"At first I heard just one gunshot, and there was a pause, and then there were multiple continuous shots," stated Amporn Niamfuang, who operates a restaurant 50 meters from the school gates. "Students were running scared and pouring onto the street. Young girls were holding each other's hands and crying."
Emergency responders and tactical units from the Plai Bang Police Station secured the perimeter within 30 minutes, allowing medical crews to evacuate the wounded. Authorities confirmed that all five fatalities inside the school were teachers and staff members who stepped in or were caught in the hallway gunfire. Fifteen of the injured suffered non-gunshot trauma sustained while frantically leaping from windows or crowding narrow stairwells to escape.
Second School Shooting in 2026 Sparks Calls for Gun Control
The August 7 attack marks Thailand’s second major school shooting in 2026, following a February incident at an educational facility in Hat Yai that left a teacher dead. Despite maintaining strict legal regulations on civilian firearm acquisition, Thailand has one of the highest rate of gun ownership in Southeast Asia, with millions of registered and illicit firearms in circulation.
The tragedy has intensified public pressure on the government to strengthen laws surrounding firearm storage, particularly in households with young dependents. Addressing media outlets outside the hospital where victims were receiving care, Deputy Interior Minister Polapee Suwunchwee underscored the government’s commitment to reviewing safety protocols.
"We are prioritizing full medical care for the injured while authorities conduct a thorough investigation into how the minor accessed a locked firearm," Deputy Interior Minister Polapee Suwunchwee stated in an official release.
Prime Minister Charnvirakul announced immediate legislative plans to restrict public firearm transport, emphasizing that new regulations will strictly limit who can carry weapons outside private residences.
What's Next: Investigations and Community Support
In the immediate aftermath of the tragedy, local authorities and school administrators have initiated a series of response measures:
- Forensic and Ballistics Analysis: The Royal Thai Police are analyzing digital logs, CCTV footage, and ballistics data to establish a comprehensive timeline of the suspect's movements from his home to the school.
- Psychological Services and Campus Closure: Debsirin Nonthaburi School has suspended classes indefinitely while the Ministry of Public Health deploys mobile counseling units to support surviving students, families, and staff.
- Legislative Cabinet Review: The Thai Cabinet is scheduled to convene an emergency session to review proposed gun control reforms targeting firearm storage requirements and minor access prevention.
