A report of possible gunfire at Southwestern College led to a brief lockdown of the campus Tuesday.

Police received a single report of possible gunfire on the third floor of the library of the Chula Vista community college about 12:45 p.m., said campus spokeswoman Lillian Leopold.

Officers evacuated and searched the structure while placing the Otay Lakes Road campus on lockdown as an added precaution.

Finding no evidence of a shooting, police gave an all-clear about 1:45 p.m., after which the roughly 15-minute lockdown was lifted and normal campus activities resumed, Leopold said.

It was unclear what prompted the apparently unfounded report of gunfire, the spokeswoman said.
