A murder investigation has been launched after a man who was punched in the head outside a north west London job centre before Christmas died in hospital.
Petru-Sorin Doleanu, 41, died from a significant brain injury on March 29 nearly three months after being approached by an unknown man as he stood with two friends.
CCTV has been released by murder detectives of a man walking along the street around the same time as the fight in St John’s Road, Wembley at 9pm on December 17.
The next day paramedics were called to a home in District Way after Mr Doleanu became unwell.
His friends told paramedics that he had been punched in the head and paramedics alerted police.
Petru-Sorin was taken to hospital where he was found to have a significant brain injury.
He remained there until the evening of March 29 when he sadly died. His family is being supported by specialist officers.
DI Jack Stilwell, leading the investigation, 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.
“Our investigation has determined that Petru-Sorin was with two friends near the Job Centre in St John’s Road, Wembley.
“They were approached by an unknown male. There was an altercation and Petru-Sorin was assaulted sustaining the injuries that led to him being hospitalised the following day.
“We have carried out extensive enquiries and have released a CCTV image of a man we want to speak to about this incident. I urge anyone who recognises the man in the picture to come forward.”
