NONTHABURI, Thailand — A student shot several people at a high school outside Bangkok on Friday morning, killing at least five and wounding several others, according to authorities, who said the gunman also appeared to have separately killed his two grandparents.
The gunman took his own life, officials said.
Five school staff members, including teachers and administrators, died in the shooting around 10 a.m. at Debsirin Nonthaburi School in Nonthaburi province northwest of Bangkok, Deputy Interior Minister Polapee Suwunchwee said at the scene.
The shooter also killed his two grandparents at home prior to the school shooting, Suwunchwee said.
Prime Minister Anutin Charnvirakul, speaking after touring the school, confirmed reports that the shooter was 14 years old and killed himself. He said the boy, who lived with his grandparents, had shown signs of stress connected to school.
The gun, described by police as small and compact, was legally registered to his grandfather, he said.
About an hour after the shooting, people stood outside comforting one another as police and first responders walked around the co-educational state school, which has an enrollment of about 3,000 students ranging from 12 to 18 years old.
A witness told reporters that students hid inside a classroom while they heard gunshots from another building before police officers knocked on the door and cleared a way for them to leave the building.
Bangyai Hospital, about 5 kilometers (3 miles) from the school, said 23 people were injured and 10 were in critical condition, with most suffering gunshot wounds. Earlier reports gave conflicting casualty numbers.
Police find grandparents dead at family home
After the school shooting, police went to the home of the shooter’s grandparents but the door was locked and there was no response to their calls, regional police Commander Wattana Yeejeen said.
Officers broke the door lock and found both the grandparents had died of apparent gunshot wounds, Wattana said.
Several family members of the alleged shooter, including his uncle and sisters of the grandfather who were at the family home while police investigated, said he usually kept to himself and was a good student.
The family members said they were unaware of any troubles he faced at home or school.
Thailand has high rate of gun owners
Thailand has one of the highest rates of gun ownership in Asia, second only to Pakistan but far surpassing its Southeast Asian neighbors.
Data collected in 2017 by the groups Small Arms Survey and GunPolicy.org in their last extensive international study found civilian gun ownership in Thailand was about 15.1 guns per 100 people, compared with less than one per 100 in neighboring Malaysia.
Thailand had 3.49 deaths by firearms per 100,000 people, according to 2023 statistics published by World Population Review. That puts it well behind parts of Latin America and the Caribbean, but relatively high in Asia. Only the Philippines is higher in Southeast Asia.
In February, a 17-year-old stole a gun from police and opened fire at a public high school in southern Thailand, briefly taking people hostage in a two-hour attack that killed one person and injured two others.
A 14-year-old boy was accused of a 2023 shooting at a major Bangkok shopping mall.
