FORMER Accrington Stanley captain Peter Cavanagh hopes a new Crimewatch appeal will find the man who killed his brother with a single punch four years ago.

The Reds’ captain, who left the club in June, has led appeals ever since his brother Anthony was hit to the ground while enjoying a night out in Liverpool.

The 22 year old, a Royal Navy Seaman, was on shore leave during the incident on 24 September, 2005.

An appeal aired on BBC’s Crimewatch last month,with Anthony’s mum Pat and sister Jennifer explaiingd how Anthony was punched in Concert Square after accidentally bumping into a man in the city’s Walkabout bar.

He was knocked unconscious and died in hospital 11 days later.

Peter said: "It beggars belief how someone could do this.

"Each time we have a breakthrough with the police it’s pleasing, but first and foremost we miss him.

"I can only reiterate what’s been said before – if anyone has got any kind of information, no matter how small or insignificant it may seem, it could be vital.

"We need to bring justice for what they’ve done to our brother and son.

"Until we do, it’s going to be difficult to move on."

Since the show aired, the BBC received around 15 calls and text messages including one from an anonymous caller with vital information on the attacker. The police are appealing for the caller to come forward and are looking for the man in the white T-shirt seen in the CCTV footage.

Detective Chief Inspector Tim Keelan said: "I would urge anyone who was in the bar and witnessed the assault, or who has any information which could help with our inquiries to come forward.

"In particular I would appeal to this man featured in the CCTV stills, or anyone who knows them, to come forward as they could have vital information which could help us further our inquiries.

"Anthony was out to enjoy himself with friends and was due to return to his ship on the Monday."

He added: "We would like to be able to offer the family and friends some closure by finding out what happened on the night and finding the person responsible for the attack."

Anyone with information is urged to call 0151 777 4065, or Crimestoppers anonymously on 0800555111.
