UPDATE: Reports are emerging that the incident was a fight between two kitchen staff, with one stabbing the other with a large kitchen knife. The singer was ridiculed previous year after he posted tweets to his 7.5 million followers saying shots had been fired inside Selfridges on London's Oxford Street... The authorities said that no firearms were involved and it is not being treated as a terror-related incident. I thought he was raining punches down, but then I saw the knife.

"Other staff were standing around - they didn't want to get too close because he had a massive knife".

Armed Metropolitan police were called to the record label's office shortly after 11am this morning (2nd November). The other guy was taken to the other end of the canteen to calm him down.

The witness added that there were two pools of blood on the floor, while another woman looked like she had been hurt after apparently falling over in the commotion. "Evacuations have taken place as a precaution", the force said in a statement. One person was arrested and armed police remain at the scene.

The police previously said that firearms officers and the London Ambulance Service were at the scene. At this time we believe two people have suffered injuries.

Sony Music's offices are in upmarket Kensington, west London, which is the home to several worldwide embassies and a royal residence, Kensington Palace, meaning there is routinely a visible police presence in the area. "It is not being treated as terror related", it stated.

Eyewitness Maithreyi Seetharaman told CNN that she could see around a dozen police cars, multiple armed officers and two ambulances at the scene as the incident unfolded.
