A man has died three months after being punched in the head.
Police have released a CCTV image of a suspect they want to speak to after Petru-Sorin Doleanu, 41, died on 29 March.
Mr Doleanu was with two friends in St John’s Road in Wembley, north London, when they were approached by a man at around 9pm on 17 December 2021.
Officers have said an “altercation” followed and Mr Doleanu was assaulted.
Mr Doleanu became ill the next day and was taken to hospital, where he remained until he died.
A post-mortem examination gave the causes of death as pneumonia and a head injury.
Detective Inspector Jack Stilwell said: “The past few months have been extremely challenging for Petru-Sorin’s family and friends.
“While it has been clear for some time that his injuries were extensive, his death has understandably been very difficult for them to come to terms with.”
