British police on Friday said that two men were arrested after a stabbing incident in central London at the headquarters of Sony Music.

The injuries were not life-threatening, Scotland Yard said, adding that "they were both arrested at the scene on suspicion of causing grievous bodily harm."

Sony Music later said two members of a catering team at the company's London office had been "involved in a violent altercation" that was being investigated by police.

Police said the men were taken to hospital.

Armed police officers as well as the London Ambulance Service were dispatched to the scene.

The incident was not bring treated as terrorism related, the statement said, but the building was evacuated as a precaution.

A witness told the Evening Standard: "There was a lot of shouting and commotion. It looked like they were having a fight."

"One had fallen over and was on his back and the other was standing over him. I thought he was raining punches down, but then I saw the knife," the unnamed witness added.
