Multiple YouTube employees also took to Twitter to raise the alarm, indicating that the building was being locked down as police investigated.
I looked down and saw blood drips on the floor and stairs. Peaked around for threats and then we headed downstairs and out the front.

I got evacuated outside with my hands up. I’m with other people. I don’t think the shooter’s been found that I know of. I saw blood drops on the stairs I walk up everusay. I’m shaking. This is surreal. I hope my colleagues are okay.
