PERRIS, Calif. (KABC) -- A high school in Perris is under a shelter-in-place order Friday after a loaded firearm was located on campus, according to the school district's police.

The student was removed from campus following the arrest and will be booked into a Riverside County Juvenile Detention Center, police said. No injuries were reported.
Video from AIR7 showed a big scene outside the high school.

No additional firearms were located after VVDPD's investigation. The Riverside County Sheriff's Department Bomb Squad and their K9 unit also assisted.
