Popular video website, YouTube has become the latest victim of America’s relentless gun violence. On Tuesday, a woman opened fire at YouTube’s headquarters near San Francisco, wounding at least three people before taking her own life.

Employees of the video website were said to have scrambled into the surrounding streets for safety during the incident.

Police did not release any further information on the suspect or comment on her possible motives for the shooting rampage at the Silicon Valley offices of YouTube, a service owned by Alphabet Inc’s Google.

But a US government security official that the shooting had no known connection to terrorism.

A YouTube product manager, Todd Sherman, described on Twitter hearing people running, first thinking it was an earthquake before he was told that a person had a gun.

“At that point every new person I saw was a potential shooter. Someone else said that the person shot out the back doors and then shot themselves,” Sherman said on Twitter.

“I looked down and saw blood drips on the floor and stairs. Peaked around for threats and then we headed downstairs and out the front,” Sherman said.

Responding to the report of gunfire, police officers entered the building and located at least four people with gunshots, San Bruno Police Chief Ed Barberini said at a news conference.

One of them, a woman with a self-inflicted wound, was dead, he said, and she was believed to be the shooter.
