Omer Jama Abdi, 35, died after he was assaulted in St John’s Road last year

Detectives are offering a £20,000 reward for information leading to the killers of a man who was attacked in Wembley on St Valentine’s Day last year.

Omer Jama Abdi, 35, who lived in Wembley, was found unconscious in St John’s Road on February 14 last year at 2.20am.

He was rushed to hospital where he died shortly after arrival.

An initial post-mortem examination failed to ascertain the cause of his death but further tests ruled he died of coronary heart disease caused by the assault he suffered.

Investigating officers believe Mr Abdi, who is Somalian, was assaulted by two compatriots in St John’s Road shortly before he was found dying in the street.

Last year, detectives released the image of a man they wished to speak to in connection with the investigation.

He is believed to be in his mid-30s and Somali in appearance.

He has never been traced and the hunt is still on to find him.

CCTV images of a silver three-door Vauxhall Corsa and a dark coloured Vauxhall Astra, both captured near the scene, were also released.

The occupants of both cars have yet to be traced too.

Officers have also released images and footage of potential witnesses seen on CCTV.

A group of three men were seen walking on St John’s Road at around 2.05am and a single man took the same route five minutes later.

Detective Inspector Jamie Stevenson, who is leading the murder hunt, said: “It is now one year on since Omer died and his family is still no nearer to seeing those responsible brought to justice.

“There are a number of people we wish to identify and trace so we can speak to them about Omer’s death and we hope the people will recognise themselves on the CCTV footage and images and call us.

“We are also still keen to hear from anyone who knew Omer, that hasn’t spoken to police and can help us identify anyone that he may have had any altercations with.

“I hope that following this passage of time that there are people still out there that have information on what happened on the night of his death that now feel they can come forward and share this with police.

“I am also asking the Somali community to have confidence in the Met, and that any information that they have for us will be treated in the strictest of confidence.

“If preferable we have Somali speakers on hand to talk to anyone with information.”

Anyone with information is asked to call the incident room on 020 8358 0200; a dedicated Somali speaking line dial 020 8358 1241; or Crimestoppers anonymously on 0800 555 111.

A 39-year-old man arrested at an address in Wembley on February 14 last year was bailed and later released with no further action on August 20.
