A bomb threat forcing the evacuation of a high school in Pacific Heights on Wednesday morning turned out to be the work of a prankster, as police uncovered no evidence of foul play.
Responding to a 911 call, police cordoned off the block in front of Metropolitan Arts and Tech High School, located at 2340 Jackson St., at about 9:15 a.m., but bomb-sniffing dogs found nothing of merit after a 90-minute search, San Francisco Police Department Lt. Teri Barrett said .
"After a standard search following the protocol we have with our city schools, we determined there was no threat," Barrett said.
Metro teacher Chris Rea said someone called the school from a nearby pay phone to make the threat.
The school’s approximately 350 students and 40 faculty members waited across the street from the building as police carried out their search.
Traffic was blocked on Jackson Street between Webster and Fillmore streets. The 24-Divisadero Muni bus line was temporarily diverted while police cleared the scene.
