Facebook's San Francisco-area HQ secured after threat made: police
Police searched and secured the headquarters of social media giant Facebook Inc on last night after receiving a threat against the company, which San Francisco-area authorities said turned out to be "totally not credible".
Facebook personnel held employees at the campus until officers were on scene, Menlo Park Police Department spokesman Dave Bertini said. Police officers allowed Facebook staff to leave at about 8:30 local time.
"It was a totally not credible, unsubstantiated threat," Bertini said, though he declined to say what the specific threat was. "I am not even sure that it was specifically to the Menlo Park campus of Facebook."
Facebook declined to comment on the incident.
