A MAN dressed as Elvis who was celebrating his own stag do was knocked unconscious and suffered three breaks to his jaw.

Police said the unprovoked attack was "no laughing matter" - and said the unlucky groom-to-be would remember his pre-wedding celebrations for all the wrong reasons.

The 33-year-old man was attacked outside Rainbow Taxis on Wigan Road, Ashton-in-Makerfield, at about 5.45am on Sunday.

The victim had been enjoying a night out with his friends celebrating his stag do and was waiting for a taxi when he was approached by the offender, who initially asked him for a cigarette.

Without provocation, the offender then punched the man in the face, knocking him unconscious.

Bizarrely, the assailant then apologised.

When the man came to, he got a taxi to Wigan Hospital where he underwent surgery for three breaks to his jaw.

The offender is described as being white, bald and wearing a grey or dark jumper.

Police are now appealing to anyone with information to come forward.

Det Con Cameron Hackett said: "Quite what prompted the offender to launch into a totally unprovoked and needless attack only he can know.

"Maybe he took exception to what the victim was wearing or maybe he was just drunk but whatever his motive, it was a senseless attack on a man who was simply out celebrating his upcoming nuptials.

"This is no laughing matter, as this man will remember his stag do for all the wrong reasons.

"He had to undergo surgery to repair three breaks to his jaw not to mention the emotional upheaval at a time when he should be planning for the happiest day of his life.

"We need to find whomever is responsible for this attack so I would appeal to anyone who has information to come forward.

"If you witnessed the altercation at the taxi rank or you suspect who may have been involved, then please call us."

Anyone with information is asked to call police on 101 or the independent charity Crimestoppers, anonymously, on 0800 555 111.
