Manchester Police are hoping Hammers’ fans can help in their investigation of a Good Samaritan who was stabbed when he went to the aid of a father and son involved in a row following the away game with Man City on May 1.

The injured man ended up in hospital with a puncture wound to his ribs for his trouble.

He was attacked as made his way home from the game along a cut through between Gurney Street and Palmerstone Street, Clayton, when he saw two men arguing with a man who was with a young boy, aged five-seven, wearing a replica West Ham shirt.

The victim intervened and was confronted by the two men, both wearing City replica shirts.

Det Con Nick Kershaw said: “It would seem that the exchange between the two offenders and the other man was enough of a concern to the victim for him to intervene and he has been violently assaulted for his troubles.”

Anyone with information is asked to call police on 0161 8563914 or Crimestoppers, anonymously, on 0800 55 111.
