WASHINGTON (Circa) -- Police have evacuated Facebook and Instagram's headquarters after they received reports of a bomb threat.
The Menlo Park, Calif., Police Department got word of a potential incident through an anonymous tip shared by the New York City Police Department. No details were provided about what the threat consisted of, according to KGO. An alert was then issued around 5:22 p.m. Pacific time.
In a tweet, the police department said "Police activity in the 200 block of Jefferson Drive/Constitution Drive in Menlo Park due to a bomb threat." Subsequently, they also said "The building has been evacuated and the bomb unit is on scene."
Video from the scene shows a fire alarm ringing inside a building with Instagram's logo front and center. There also does not appear to be an immediate sense of urgency among officials who have reported to the scene. Police are urging residents in the area to stay away.
Tuesday's evacuation of Facebook comes after CNN's New York bureau was forced to evacuate last Thursday night. The network was in the middle of a live broadcast when they abruptly went to a commercial break. Police responded to a bomb threat but issued an all clear an hour later.
This is a developing story.
