On Tuesday afternoon, news of an active shooter at YouTube’s headquarters in San Bruno, California spread across social media as employees took to Twitter to share details of the shooting.
San Bruno police chief Ed Barberini has since updated press to share that one person has been confirmed dead of a possible self-inflicted gunshot wound, while four to five others were taken to the hospital where they are being treated for injuries. Police believe the deceased to have been the shooter.
Earlier in the day, San Bruno police confirmed that they were responding to an active shooter near the company’s campus, urging people to stay away from the area.
An employee at the company, Vadim Lavrusik, was one of the first to take to social media with updates from inside the building. “Active shooter at YouTube HQ. Heard shots and saw people running while at my desk,” he wrote. “Now barricaded inside a room with coworkers.”
BuzzFeed News also shared photos from social media that reportedly showed people running out of the building and being escorted by police with their hands raised.
Google, which owns YouTube, tweeted that they were cooperating with authorities, “Re: YouTube situation, we are coordinating with authorities and will provide official information here from Google and YouTube as it becomes available.”
City Manager Connie Jackson also told BuzzFeed News that police received multiple calls of shots fired inside and outside the building.
