Bomb Threat Briefly Locks Down Mira Costa High

A bomb threat locked down Mira Costa High School on Friday morning, police said.

The lockdown was initiated at 10:05 a.m. when the school received the threat, according to the Manhattan Beach Police department.

Police and school staff did a cursory search of the classrooms and school grounds and determined the threat was not credible. School resumed as usual at 10:30 a.m., 25 minutes after it was locked down.

It was not clear at this time how the school received the threat. Last December, classes were canceled at Mira Costa because of what police called ’specific threats’ at that time.
