UPDATE 1 P.M.: Students were released from Washington High School on Friday afternoon hours after a man called the school and reported a bomb was on campus, district officials said.
Students left the school, located at 599 30th Ave., at 12:30 p.m., the time the school was set to let out because of final exams this week.
Two nearby schools, Lafayette Elementary and Presidio Middle schools, were locked down for several hours as well, but the lockdown was lifted around 1:30 p.m.
Police have been speaking continuously with the man who allegedly called in the bomb threat, said San Francisco police spokesperson Officer Grace Gatpandan.
Officers have been canvassing Washington High with K-9 units and nothing suspicious had been found as of 1 p.m.
“There’s no immediate threat,” Superintendent Richard Carranza told reporters outside district offices Friday afternoon.
