Youtube workers are reportedly fleeing for their lives as an active shooter was heard letting off shots at their offices in San Bruno, California shortly after 9pm Irish time.
Police are at the scene where at least two people have been shot according to various reports coming out of the U.S.
Vladim Lavrusik, a product manager at the company, tweeted that there is an active shooter on campus.
Todd Sherman, another product manager, said he was in a meeting when he “heard people running because it was rumbling the floor”.
He posted: “First thought was earthquake. After existing the room we still didn’t know what was going on but more people were running.
“Seemed serious and not like a drill. We headed towards the exit and then saw more people and someone said that there was a person with a gun.”
