A building on Facebook's campus in Menlo Park was evacuated Tuesday evening after a bomb threat, police said.
Menlo Park police said the threat was called into the New York Police Department's Crimestopper unit, which in turn notified local authorities.
According to Menlo Park police, the bomb threat was made to a Facebook building at 200 Jefferson Drive.
Facebook management, as a precaution, requested buildings in the surrounding area be evacuated, police said. The police response also diverted traffic around the area.
The San Mateo County Sheriff's Office bomb squad responded to the scene and after a sweep of the area found no suspicious package or devices.
Police then cleared the scene after giving the area an all clear.
