San Dimas High School Campus Determined Safe After Student Reports Possible Man with a Gun

San Dimas Sheriff’s Station deputies responded to San Dimas High School for a man with a gun call. The incident began on Friday, February 23, 2018, at approximately 10:00 p.m., at 800 Covina Boulevard, San Dimas.
A student from the school called a classmate and told her when she was leaving the school, after a rehearsal activity, she saw a man wave a gun near the trash dumpsters.
Deputies responded to the school, searched the campus and ensured the students and teachers remaining at the activity were safe. After the campus was rendered secure, and no one with a gun was found, deputies escorted the remaining students and staff to their vehicles, and/or a safe place to be picked up by parents. 
It was later determined, that it was possible the caller saw a school employee emptying the trash, which in the dark and from a distance, may have looked like a gun.
No gun was found, nor was a gun seen by anyone else on campus.
