THIS is the moment hundreds of YouTube employees were led to safety after police were called to reports of an active shooter at the internet giant’s headquarters.
Workers with their hands above their hands were evacuated from the office block in San Bruno, California this afternoon local time.
Gunshots were reported and police have warned people to stay out of the area.
YouTube owner Google said it was investigating a possible “gunfire incident”.
Local reports have said the shooter is a woman and that two people have been shot, although this is not confirmed.
Nearly 2,000 people work at YouTube HQ.
Nearby workers reported that their offices were also on lockdown.
