Police in San Bruno, Calif., April 3 confirmed reports of shots fired this afternoon at Google-owned YouTube headquarters.
“We are responding to an active shooter. Please stay away from Cherry Ave & Bay Hill Drive,” San Bruno police said on a Twitter post.
Police later released a timeline of events. Officers arrived on scene at 12:48pm, two minutes after the first call, and immediately began searching for a possible suspect. Arriving officers encountered numerous employees fleeing the building. Officers encountered one victim with an apparent gunshot wound to a lower extremity at the front of the building.
