A man has been stabbed to death outside a five-star hotel in west London.

Police, paramedics and London’s Air Ambulance were called to the Park Tower Hotel on Seville Street, Knightsbridge, just before 21:30 BST on Wednesday.

Paramedics treated the 24-year-old for knife wounds but he died at the scene, the Metropolitan Police said. No arrests have been made but officers are working “to establish the circumstances of what happened”.

A spokesperson for the hotel said the incident did not involve any of its guests or staff.

The area where the incident happened is generally known for its luxury shopping, multimillion-pound residences and landmarks like Harrods and Hyde Park.

Police have closed off the pavement surrounding the hotel and adjacent restaurant Nusr-Et, run by Turkish chef Nusret Gokce, aka “Salt Bae”.

Supt Owen Renowden, who leads policing in Kensington and Chelsea, said: “We are aware of reports that this incident was a robbery.

“Although this is an active line of inquiry, we are keeping an open mind about all possible motives and the exact circumstances are still to be determined.

“We understand the impact this incident will have on the local community and you will see extra officers in the area to help answer any questions or concerns.”

The man’s family have been informed and are being supported by specialist officers.

Kaya Comer-Schwartz, London’s deputy mayor for policing and crime, called the stabbing “appalling” and said there would be “increased high-visibility police patrols” in the area.

She said: “Knife crime has no place in our streets of communities.”
