Seven people have been arrested after four men were stabbed in south-east London, the Metropolitan Police has said.

One of the men remains in a critical condition in hospital, while the other three are being treated for injuries that are not believed to be life-threatening.

Paramedics and the London Air Ambulance were called to Bromley High Street at about 14:20 BST on Thursday.

A fight is believed to have taken place in or around KFC, and a statement from the company is expected.

The high street is currently closed both ways from Ringers Road to Ethelbert Road.

Police remain at the scene and say there is not believed to be any wider threat to the public.

One witness, the manager of Merkur Slots gambling shop, said she saw “a fight spill out” on to the High Street.

She said she became “very worried”, and locked three customers inside the premises to wait for the situation to calm down.

She said the customers remained inside and that the shop was still closed.

Vinnie Guadagnino, who lives on Bromley High Street, said he saw a large emergency response with multiple police cars and about 10 officers on foot.

“Police cars kept coming, then within the next half hour there were multiple fire engines and people gathering.

“Then there was a drone overhead and helicopters and an air ambulance – so a massive emergency service response.”

Peter Fortune, Conservative MP for Bromley and Biggin Hill, said on X that residents “would have safety concerns” and he would remain in contact with the police as they investigate.
