No bomb found after threat on Facebook campus

Police said no explosive device or suspicious package was found Tuesday evening in an office building on Facebook’s main campus in Menlo Park.

At 4:32 p.m. Menlo Park police received a call from the New York City Police Department Crime Stopper unit about a bomb threat at a building at 200 Jefferson Drive in Menlo Park.

The building, which is just one on Facebook’s campus, was evacuated and bomb detection dogs went through it looking for a device or something suspicious, according to Menlo Park police.

At about 6:30 p.m., a Facebook official said employees were safe.

As of 7:50 p.m., Menlo Park police had deemed the area safe.

New York City police heard about the bomb threat through an anonymous tip. Facebook officials asked as a precaution that other nearby buildings be evacuated and police helped do that.

Menlo Park police also said officers also surrounded the building to keep people away and diverted traffic temporarily.

New York City police this evening were not able to provide any more information about the threat.
