Police detained a 14-year-old boy on Wednesday after he entered a secondary school in Kamphaeng Phet and fired a pistol. No injuries were reported.
The teen entered the compound of Wachiraprakarn Witthayakhom School at 2pm and fired about eight bullets from his 9mm handgun into the sky, media outlets reported.
Teachers and students were ordered to stay inside classrooms and lock the doors for safety.
The suspect, whose name was not disclosed, is currently under police detention.
Daily News reported the gunman was a student of the school who was serving a suspension. He reportedly told officers he had returned to the school looking for a teacher.
According to local media reports, the boy had broken into his father’s car and stolen the handgun used in the shooting. His father is a patrol officer at the Muang district police station.
Parents quickly went to the school to bring their children home.
The incident in the northern province was the latest in a handful of incidents, along with some false alarms, that have had students and parents on edge recently.
They followed an attack on Aug 7 at Debsirin Nonthaburi School that killed seven people, including the gunman, who had shot his grandparents to death earlier.
