Santa Barbara Middle School was evacuated Tuesday morning after authorities received a phone call warning that there was a bomb on the campus, according to the Santa Barbara Police Department.

Following its own safety protocol, the Middle School took all its students and staff away from the campus at 1321 Alameda Padre Serra on the Riviera, said police Sgt. Ethan Ragsdale.

He described the bomb threat, which was phoned in to police dispatchers, as “unsubstantiated,” and said it came from a number registered in Florida.

Officers responded to the private school campus with a bomb-trained canine and searched the campus.

“At this point, we’re treating it like it’s a real thing,” Ragsdale said, adding that all students and staff were “safe and accounted for.”

Classes were canceled for the remainder of the day, he said, and students were being escorted to the Santa Barbara Bowl parking lot off East Anapamu and Milpas streets for pick-up for their parents or guardians.
