Four students at a Kalamazoo High School have been arrested after one fired a handgun inside the school's restroom.

The Kalamazoo Department of Public Safety says Loy Norrix High School was placed on lockdown Tuesday morning after a 10th-grade boy accidentally fired the gun in the boys bathroom.

Three other 10th-graders helped try to hide the gun, which police eventually found inside the backpack of one of the students.

All four students have been taken to the Kalamazoo County Juvenile Home.
