Police have charged two teenagers with the murder of a man in Greater Manchester on Friday.
Police say the attack has no connection with the Labour Club
Asaf Mahmood Ahmed, 28, of Broomfield Road, Bolton, suffered severe head injuries in the attack near Derby Ward Labour Club in Bolton.
Mr Ahmed was on his way to shops when he was attacked.
In the early hours of Christmas Day, Jason Bolton, 18, and a 15-year-old boy were charged with his murder. A court date has yet to be set.
A post-mortem examination to establish the cause of Mr Ahmed's death had been inconclusive and further tests were being carried out, police said.
Superintendent Andy Durkin, of Greater Manchester Police, said: "He had passed a shop that was open en route to the place where he sustained his injuries and I would appeal for anyone who can explain why, or indeed has witnessed anything prior to this incident or during it that may assist in the investigation, to contact police," he said.
Police said the attack had no connection with the Labour Club but have appealed to customers who may have seen the incident to come forward.
