A man has been arrested as police continue to investigate a murder.

Petru-Sorin Doleanu, 41, suffered a significant brain injury after he was punched in the head when walking near the Job Centre in St John’s Road, Wembley, on December 17, 2021.

Police arrested a man, 24, on suspicion of murder after he handed himself in to a north London police station on Friday (July 15).

He was released under investigation the following day.

Doleanu was with two friends in Wembley when they were approached by an unknown man and a fight broke out.

Shortly before 11am the next day, he became unwell and was taken to hospital as his brain injury was treated.

He remained in hospital until March 29 when he died.

Now an image of a man, who is not considered a suspect, has been released as police believe he may have witnessed the assault.

Detective Chief Inspector Jim Eastwood, who is investigating, said: “The past few months have been extremely challenging for Petru-Sorin’s family and friends and his death has understandably been very difficult for them to come to terms with.

“Our investigation continues at pace and, in addition to the arrest, we are continuing to carry out a number of enquiries.

“We have released an image of a significant witness whom we would like to speak to.

“We believe this man saw the attack and we are keen to speak to him to ensure the person responsible for Petru-Sorin’s murder is brought to justice.

“Please be assured, you are not in any trouble and your help could ensure a dangerous man is removed from the streets of London and Petru-Sorin’s family get the closure they deserve.

“I would urge anyone who recognises the man in the CCTV to come forward.”

Anyone who recognises the man in the image, or who has other information about the incident, should call police on 020 8358 0300 or 101, giving the reference 2254/18dec.
