Update, 11:15 p.m.: Multiple news outlets have identified the YouTube shooter as Nasim Aghdam. Details remain scarce about the identity and motivation of the woman, who authorities say opened fire with a handgun at YouTube headquarters Tuesday, injuring three people, before taking her own life. ABC7 News in San Francisco, however, reports Aghdam is a YouTube user who maintains “a website with an alleged manifesto that targets YouTube for censorship and demonetization of her video content,” indicating the shooting could have been motivated by a decline in her viewership and loss of revenue. Contrary to earlier reports indicating the shooter knew someone at the company, ABC7 reports Aghdam is believed to have no personal relationship with anyone at YouTube. The shooting took place in a courtyard inside the offices of the company, which, the New York Times reports, maintains light security for employees that requires badges for entry but no visible metal detectors or armed guards.
Update, 9:20 p.m.: San Bruno Police Chief Ed Barberini clarified that there were three shooting victims not four at YouTube headquarters, the fourth person was injured fleeing the building. The names of the three victims that were taken to Zuckerberg San Francisco General Hospital have not been released, but Barberini said a 36-year-old man was in critical condition, a 32-year-old woman in serious condition, and a 27-year-old woman in fair condition. The shooter, a woman, then shot and killed herself, according to police.

Original post, 4:45 p.m.: There is an active shooter in the area of YouTube’s headquarters in San Bruno, California, police confirmed to The Hollywood Reporter on Tuesday.
The San Bruno Police Department also sent out a tweet warning of police activity in the area on Tuesday afternoon:
The San Bruno City Manager told KRON4 that operators have received 911 calls from YouTube, and the station also reports that employees are being led out of the campus with their hands up by police. Multiple YouTube employees and other eyewitnesses have also taken to Twitter to report on what they’ve seen on the campus. Based on these posts, it appears that many heard shots fired, and there is currently a heavy police presence in the area.
YouTube has several hundred employees, though it is not immediately clear how many of them are based in San Bruno.
