SHOTS were heard at Youtube headquarters in San Bruno, northern California.
The shots fired have injured at least two people, with many in the building fleeing to safety.
According to BBC, the authorities and ambulances were called to the area to facilitate any injuries.
Product manager for Youtube Todd Sherman recalled hearing masses on foot earlier this evening, due to running from the shots.
We were sitting in a meeting and then we heard people running because it was rumbling the floor. First thought was earthquake. https://t.co/gmolQmRXm1
