A murder hunt is under way as police revealed a man whose body was found in a park at the weekend may have been assaulted before he died.

Passers-by found the body of the man, believed to be in his 30s or 40s in Holmes Park, Wisbech, on Saturday night.

Detectives are working to identify the man, who was wearing a T-shirt and track suit bottoms.

DCI Jim McCrery, who is investigating, said: 'We are still working to identify this man and I am appealing for anyone who knows who he might be to contact police.

'There is evidence which could indicate this man had been assaulted so I would appeal to anyone who was in the area of Holmes Park on Saturday night to consider if they saw anything significant. 'Any information, no matter how insignificant it may seem, could be important to this inquiry.'

Temperatures in Wisbech had plummeted well below freezing when the body was found by two passers by, just after 9pm.

A white tent was put up where the body was found and police spent yesterday making house to house around the area.

Daz McCoo, who runs a food van called Thai-Dee snack bar on Holmes Drive, arrived after the body had been found. His wife had been working in the van when the body was found.

He said: 'The two lads rang the police. Two police officers arrived first and one police officer stood by the alley way and refused to let anybody go down there. Then a patrol car and paramedics arrived.

'A tent went up at about 1am and the forensic team arrived. This street was like London at 2am on a Saturday night.'

Anyone with information should DCI McCrorie on 0345 456 4564.
