San Luis Obispo police say a bomb threat called into Pacific Beach High School was a hoax.
Police say the high school received a call at around 10 a.m. on Friday from someone claiming that a bomb had been placed in one of the buildings on campus.
Students and staff immediately evacuated and police and the San Luis Obispo County Sheriff's explosives-detecting K9 responded to the school.
Police say a sweep of the campus found no explosive material and investigators determined the call had originated from Canada.
