A student was struck with a gun by one of several people who walked onto a high school campus Thursday afternoon near Pomona.
The attack was reported at about 3:30 p.m. Thursday at Diamond Ranch High School near the community about 30 miles east of Los Angeles. Video from the scene showed a scuffle in what appeared to be a hallway or common area.
Deputies responded to a report that a "group of males" entered the campus armed with guns and assaulted a student, according to the sheriff's department. Deputies spoke with the victim, who said he was approached while sitting outside the school by a group that began arguing with him.
It was not immediately clear whether the individuals were associated with the school.
