Mar Vista High School was placed on “secure campus mode” after multiple phone threats were received Thursday, San Diego County Sheriff’s Deputies said.
The phone calls began at approximately 1:06 p.m. from a phone number verified “as not being a real number,” officials said. Laughing could be heard in the background, deputies said. They believe the calls were placed by juveniles.
Deputies made a sweep and determined the threat wasn't credible.
The Sheriff's Department takes every threat seriously and will conduct a thorough investigation of the incident
Mar Vista High School is part of the Sweetwater Union High School District and is located on Elm Avenue in Imperial Beach.
