Three people were injured after being shot at YouTube’s headquarters in San Bruno, California, on Tuesday, by a suspect who died at the scene from an apparent self-inflicted gunshot wound.

The injured were taken to Zuckerberg San Francisco General Hospital. Those include a 36-year-old male who is in critical condition, a 32-year-old woman in serious condition and a 27-year-old woman in fair condition, according to reports.

Police have identified the shooter as Nasim Najafi Aghdam. The 39-year-old woman’s last known address is in the San Diego area. It’s believed she used a 9-millimeter handgun.

Some reports suggested the violence was related to a domestic dispute, but it seems Aghdam was upset with YouTube for taking down some of her videos and the resulting loss of revenue to her YouTube page. In one video, she said YouTube “discriminated and filtered” her content. It seems her channel was pro-vegan, but contained some images of animal cruelty, which YouTube deemed inappropriate.

In an email to employees, Chief Executive Sundar Pichai said he received news of the shooting around lunchtime on Tuesday. The buildings were quickly evacuated of several hundred people and the situation contained. Pichai called the shooting a “horrific act of violence” and an “unimaginable tragedy.”

There are no words to describe the tragedy that occurred today. @SusanWojcicki & I are focused on supporting our employees & the @YouTube community through this difficult time together. Thank you to the police & first responders for their efforts, and to all for msgs of support.

Vadim Lavrusik, a product manager at YouTube, wrote on Twitter, “Active shooter at YouTube HQ. Heard shots and saw people running while at my desk. Now barricaded inside a room with coworkers.” Lavrusik later tweeted that he had been evacuated and was safe, although it seems that his account was hacked sometime on Tuesday and hoax tweets were sent about the tragedy.

There are tweets being posted to his account that are definitely not from him

People described the scene as chaos as helicopters and police SWAT teams arrived at the offices. The YouTube HQ is not at Google’s Mountain View campus, but in a regular building in San Bruno, not far from San Francisco airport.

It’s thought the shooting began at 12.45 p.m. PDT as people were eating their lunch. Others said they were in meetings when it began, and after hearing a commotion thought that there may have been an earthquake.
