A loaded .45-caliber handgun went off inside a Hawaii school campus just before classes started on Monday. The bullet narrowly missed a student but injured another said police officers.

Capt. Leslie Hite, Honolulu police officer, said the gun went off when the student who pointed the gun at another student was shoved by a second student, pushing the gun away. The bullet bounced back from a lava rock wall and hit the jacket of the boy who pushed the gun away but did not hit his body.

The police do not know for sure but the bullet must have bounced off the wall a second time before it hit the right hand and thigh of another student. Minor scratches to his thigh and fingers were treated on the scene with bandages.

This is the first incident of a gun going off inside a Hawaii school, Hite said.

Before the incident, the boy who fired brought a loaded gun in school was seen sitting at the bottom of a stairway near the basketball court with a group of friends. He apparently unloaded the gun’s magazine to show it off but a bullet was already in the gun’s chamber. Hite, however, said that it is unclear if they were just playing around.

The 14-year old boy who brought the gun to school was arrested due to attempted murder, police officials said. The gun was registered to a person whose last name is not the same with the boy who shot the loaded gun. The police are still trying to find out how the boy gained possession to the gun.

The school remained open after the incident and Vice Principal Ellen Fujino assured parents that the school responded appropriately to the incident and that the children’s safety is the school’s major concern. Some parents, however, chose to pull off their children from school.
