Man arrested after two stabbed in kitchen staff row at Sony building in central London

A man has been arrested after two people were stabbed after an argument broke out between kitchen staff at Sony's London headquarters

Employees said two members of kitchen staff were "running round chasing each other" and "slashing each other up".

Sony said two members of its catering team were involved in a "violent altercation".

Images posted on social media showed armed police entering the building in Derry Street, Kensington, at around 11am on Friday.

The Metropolitan Police said two people suffered stab injuries, but they are not believed to be in life-threatening conditions.

One Twitter user inside the building posted: "Under tables at The Sony Building in a locked office because there’s banging and screaming downstairs."

She later wrote that they had been "safely evacuated", posting a video showing armed police inside the building.

Sony said in a statement: "Sony Music confirmed there was an incident at Derry Street resulting in the building being evacuated.

"Two members of the catering team were involved in a violent altercation. The incident is now in the hands of the Metropolitan Police."

The Metropolitan Police said two people "suffered stab injuries" and there was "no evidence firearms were involved".

"Officers, including firearms officers, and London Ambulance Service are in attendance," a Scotland Yard spokesperson said.

"Evacuations have taken place as a precaution.

"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."

Footage filmed from an office building opposite showed a number of armed police entering the building through the front door.

Trish Ellis, a personal assistant at the Mail on Sunday, which is based in offices opposite the building, 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.
