At least five people have been injured in a shooting at YouTube's HQ in San Bruno, California by a shooter who was reportedly female.

Four or five patients have been taken to Stanford hospital and 'multiple' have gone to San Francisco General Hospital but it is not yet clear how many have been injured. 

A worker from Carl's Jr. next door to the campus said one woman was shot in the parking lot and was brought into the restaurant to be cleaned up. 

Another witness reported seeing one woman being shot dead in the courtyard outside YouTube. 

'It did not stop. There was no mercy,' the witness told Fox News. 

Police are yet to confirm any injuries or fatalities. ABC reports that the shooter is a white woman wearing a dark top and a headscarf. 

They reportedly fired at least 20 shots, according to an unnamed law enforcement source. 

It remains unclear if the shooter has been apprehended by police or if they are even still alive.
