A suspect opened fire at YouTube’s headquarters near San Francisco on Tuesday, sending employees scrambling into the street as at least four casualties were taken to local hospitals and witnesses described blood on the floor.
The shooter, a woman, was “down” at the scene, NBC News reported. Reuters could not immediately confirm that report.
Police in San Bruno warned people in a Twitter message to stay away from the address where YouTube, owned by Alphabet Inc’s Google, is based.
“We are responding to an active shooter. Please stay away from Cherry Ave & Bay Hill Drive,” San Bruno police said on Twitter.
