The family of a chef who was attacked near Notting Hill Carnival are "inconsolable" with grief after his death.
Mussie Imnetu, who was 41 and visiting the UK from Dubai where he lived and worked, was found unconscious with a head injury outside the Dr Power restaurant in Queensway at 11.22pm on Monday (August 26).
Customers at the venue tried to help stop the attack, Scotland Yard said, and may be able to provide vital information.
Police officers provided emergency first aid until paramedics arrived.
Mussie, who worked under Gordon Ramsay and Marcus Wareing, was taken to a west London hospital where, despite the best efforts of medical staff, he died on Friday (August 30).
On Thursday, Omar Wilson, 31, of Napier Road, Leytonstone, was charged with causing grievous bodily harm with intent.
He appeared at Westminster Magistrates’ Court on August 30, where he was remanded in custody to appear at Southwark Crown Court on September 27.
In light of Mussie’s death, the offence will be reviewed in conjunction with the Crown Prosecution Service.
Scotland Yard is urging any witnesses or anyone who remembers seeing Mussie to get in touch.
Detective Chief Inspector Brian Howie, who is leading the Met’s murder squad investigation, said: “Mussie’s family, friends and colleagues in London, Dubai, Sweden and Eritrea are inconsolable after receiving the worst news imaginable – our thoughts are with them and they are being supported by specialist officers.
“Our investigation is well advanced, but we are still very keen to hear from anyone who can help piece together Mussie’s movements between 1pm when we know he left The Arts Club in Dover Street, Piccadilly, and when he arrived at Dr Power restaurant, Queensway at 10.30pm.
“If you visited the restaurant between 10pm and 11.30pm on Monday night or were in the area and saw something, regardless of the reason you were there, please do get in touch.
“Our focus is on what happened to Mussie. Did you speak with him at the restaurant or do you have any images or videos between these times that could assist the investigation?
"The attack happened around 11.20pm. Customers at the venue tried to help stop the attack; we need to speak with these people and I urge them to contact us.”
Officers will be outside the restaurant and in the surrounding area from 9pm on Monday (September 2) to hand out appeal leaflets and speak with local people one week after the murder.
Anyone with information should call the police on 101, messages @MetCC on X or contact Crimestoppers, anonymously, on 0800 555 111 giving the reference 8020/26AUG.
