A Michelin star chef who has worked with Gordon Ramsay and Marcus Wareing is critically ill after he was attacked near Notting Hill Carnival.
Mussie Imnetu, 41, was found by officers unconscious with a head injury in Queensway, west London on Monday night.
He remains critically ill in hospital with his family being supported by specialist officers.
A 31-year-old man has been arrested on suspicion of attempted murder.
The Swedish national was visiting the UK on business from Dubai where he worked as a chef.
Mussie was attacked at the Dr Power restaurant in front of other people who tried to stop the attack.
He works as Head Chef at the Arts Club in Dubai, having also worked at the Oblix restaurant in London.
Detective Chief Inspector Brian Howie, leading the investigation from the Met’s Homicide Command, said: ‘While the arrest of a suspect is a significant step in our investigation, we are still very keen to hear from anyone who can help piece together Mussie’s movements between when he left The Arts Club at 13:00hrs and when he arrived at Dr Power restaurant at 22:30hrs.
‘Customers at the venue tried to help stop the attack, we need to speak with these people and I urge them to contact us.
‘We are releasing Mussie’s name and two photos of him – one showing him on the day of the attack – in the hope that it triggers someone’s memory and prompts them to come forward.’
