Two people have been injured in a stabbing at Sony HQ in west London.
Firearms officers were called to Derry Street in central London at 11am amid reports a man with a machete has entered a building belonging to Sony Music.
Staff were evacuated from the building as a precaution. A police helicopter is hovering above.
The Met Police said: “Officers, including firearms officers, and London Ambulance Service are in attendance.
“Two people have suffered stab injuries – we await an update on their condition. One person has been arrested.
“No evidence of any firearms involved in this incident. It is not being treated as terror related.
“Officers remain on scene and the incident remains ongoing.”
Footage posted on social media from the scene shows armed police and paramedics on stand-by.
London Ambulance Service paramedics were on the scene and a stretcher was seen being taken inside the building.
What have eyewitnesses said?
Trish Ellis, a personal assistant at the Mail on Sunday who witnessed the incident, said: “It started opposite our building in Derry St, usual sirens and racket but then we heard shouting, and more and more sirens.
“A few people came out, then armed police were going in six-plus at a time, and more and more of them, but they seemed to be keeping people in the building.
“Gradually they started to release people in tens, twenties, [and] a stretcher turned up with all the medical kit on it, but just stayed outside.
“A [helicopter] appeared, still loads of armed police running up and down, and then thankfully over the time it ended up much quieter with 10 armed police standing outside, at ease.
“[An] empty stretcher went away and, thank God in heaven, all seems calm again,” she added.
