IMPERIAL BEACH (CNS) - A bomb threat prompted a lockdown Tuesday afternoon at Mar Vista High School and a nearby elementary school in Imperial Beach.
Someone called Mar Vista High School about 2:30 p.m. and claimed that six explosive devices had been planted at the Elm Avenue campus, according to sheriff's officials.
Administrators kept all students in their classrooms while deputies searched the school, Lt. Eddie Brock said. Nearby Imperial Beach School also was locked down as a precaution.
Deputies allowed administrators to let students go home in the late afternoon. Sheriff's personnel continued to search the high school into the early evening before clearing the scene.
There were no reports that explosives or any other hazardous items were found at the schools.
