Officers run toward a YouTube office in San Bruno, Calif., Tuesday.


Officers and federal agents swarmed the company's headquarters complex in the city of San Bruno around 1 p.m as multiple 911 reports came in reporting gunfire.

It is unknown if the woman shot herself or was shot by someone else, such as law enforcement.

A witness has told of discovering a bloodied victim in a carpark. Authorities say the women believed to be the shooter has died from an apparent self-inflicted gunshot wound. Barberini said officers found a wounded victim outside of the building.

Police in Northern California say they're responding to an active shooter at YouTube headquarters.

San Francisco General Hospital spokesman Brent Andrew told KPIX the hospital received patients from the incident but could not confirm a number.

Police and emergency services responded to the "active scene" after multiple emergency calls were received.

Heavily armed police surrounded the facility, with armed SWAT vehicles stationed outside.

Ambulances are at the scene and authorities have warned the public to stay out of the area.

There are also unconfirmed reports that the suspect has shot themselves. Police were seen escorting people out of the building with their hands in the air. Now barricaded inside a room with coworkers.

A project manager at YouTube Todd Sherman said there were "blood drips on the floor and stairs". "First thought was quake".

Sherman said as they headed toward the exit, they met others who said there was a person with a gun.

"At that point every new person I saw was a potential shooter".
