Santa Monica High School was cleared after a bomb threat was made on Thursday.

The threat, which came in at about 11:45 a.m., reported that a bomb would detonate in five minutes, according to a message from Principal Marae Cruce that was shared on Twitter by the Santa Monica Police Department.

Officers and school administrators swept the campus in what police described as “a precautionary search of the area.”

The school was cleared and no suspicious items were found. The lockdown was lifted and students were eventually dismissed for the day.
