Original story:

Some buildings in Facebook’s office campus in Menlo Park, California, were evacuated following a bomb threat near the area Tuesday evening.

Shortly after 5:20 p.m. local time (8:20 p.m. EST), the police issued an alert asking the public to avoid the area around the 200 block of Jefferson Drive in Menlo Park, where the offices housing Facebook and Instagram are located. The San Mateo bomb squad, along with several police patrol cars, was deployed to the scene.

According to NBC Bay Area, tips regarding the bomb threat came from an anonymous phone call to the New York Police Department’s Crimestopper Unit, which in turn informed the Menlo Park police. The police did not provide more details about the threat.

Daniel Lo Nigro, one of the employees who was working in the building which was evacuated by the authorities, tweeted about his experience.

“First time I've ever heard the evacuation alarm at work. The alarm sounded, then security came through the building I work in and asked everyone to evacuate,” he wrote.

BBC reporter Dave Lee tweeted that Facebook confirmed the ongoing investigation into the bomb threat and that an unspecified number of buildings inside the campus had been evacuated. There were no reported injuries and everyone inside the offices was deemed safe.
