\nSAN FRANCISCO (Reuters) – A bomb threat prompted authorities on Tuesday to evacuate a building at the Silicon Valley headquarters of Facebook Inc ( FB. O), police said, but gave the \u201call clear\u201d after an hours-long search turned up no sign of a device.
The New York Police Department had received an anonymous tip about a bomb threat regarding Facebook\u2019s campus in Menlo Park, California, and alerted local authorities at about 4:30 p.m., a spokeswoman for the Menlo Park police said.
Late on Tuesday, police said the building was secure, however.
\u201cThe San Mateo County bomb unit was dispatched with explosive detection dogs that conducted a sweep of the building and found no suspicious packages or devices,\u201d they said.
\u201cThe building is all clear and secure.\u201d
Menlo Park police spokeswoman Nicole Acker had said the evacuation was confined to a three-story facility on campus that was not the headquarters building, but a company spokesman said by email that \u201ca few\u201d buildings on the site had been evacuated.
Everyone was safe, Facebook and police said.
\u201cWe take the safety and security of our people at Facebook extremely seriously and are glad that everyone is safe,\u201d said spokeswoman Genevieve Grdina, adding that the firm had taken
swift action to evacuate several buildings.
\u201cWe are working closely with local authorities to investigate this threat and further monitor the situation.\u201d
Another Silicon Valley company to face a security threat in the recent past was YouTube. In April, a woman opened fire at its headquarters in San Francisco, wounding three people before she shot herself dead.<\/p>\n
