A chef who has worked under Gordon Ramsay is critically injured in hospital after being attacked near the Notting Hill Carnival, police have said.
Mussie Imnetu was unconscious with a head injury when he was found by officers in Queensway, west London, just before 11.30pm on Monday.
The police provided emergency first aid until paramedics arrived.
Mr Imnetu, 41, also worked under other acclaimed chefs Marcus Wareing and Alain Ducasse, according to The Sun.
He worked at The Arts Club in Dubai, an offshoot of the The Arts Club, described on its website as a “historic London private members’ club”.
The Metropolitan Police said in a statement on Thursday it was taking “the unusual step of naming” the victim and issuing pictures of him, “in the hope it triggers someone’s memory and prompts them to come forward”.
The statement said: “He left The Arts Club on Dover Street, W1 shortly after 1pm on Monday. He was alone and wearing a blue T-shirt and black jeans. He later bought a white baseball cap.
“He arrived at Dr Power restaurant in Queensway at around 10.30pm and again, he was alone.
“The restaurant was serving food from stalls outside and playing music. The venue and surrounding area were extremely busy with people who had been to Carnival.”
The force also said it wanted to speak to customers at the venue who tried to stop the attack, which happened at around 11.20pm.
