Family offer £20,000 to catch Adrian Cooksey's killer
The family of a man who died after he was assaulted in Wiltshire have offered a £20,000 reward for information leading to a conviction.
Adrian Cooksey, 50, from Trowbridge, died after he was assaulted near a taxi rank in Melksham on 8 March 2009.
Last year, a man was cleared of his manslaughter and the force relaunched their investigation following a review.
Police said a number of new leads were being looked at.
Speaking at a news conference on Monday, Det Ch Insp Ian Saunders said following an appeal the investigation had produced a number of previously unidentified and potentially highly significant lines of inquiry.
"For operational reasons I am unable to discuss these new lines of inquiry," he added.
The conference was also read a statement from Mr Cooksey's son Adam.
"We have decided to offer a reward of £20,000 for information which leads to the conviction of the person who took dad away from us," he said.
"He was a good man, he was kind and caring and we were a close family. We all miss him and there is not a day that goes by that we don't think about him.
"Nothing can ever ease our pain but to find out who was responsible for his death would mean we can finally start to move on."
Mr Cooksey, of Trowbridge, died on 8 March last year after he was found earlier that day with head injuries.
He had been out with friends in the town on the Saturday night and was attacked at about 0245 GMT on the Sunday.
Mr Cooksey, who ran building and plumbing firm A Cooksey & Sons, died at the Royal United Hospital in Bath when his life-support machine was switched off.
He was a well-known member of Bradford-on-Avon Cricket Club, captaining the second team and playing many times for the first team.
