A REWARD of £5,000 has been offered for information leading to the capture of the killer of a man found lying on a quiet country road.

Millions of TV viewers last night saw a recreation of the final hours of David Williamson, 58, who was murdered earlier this year.

Detectives are hoping a national appeal on the BBC Crimewatch programme will lead to new evidence in the case.

Mr Williamson was discovered on the road between Sutton-on-the-Forest and Huby, North Yorkshire, on March 26 and later died in hospital.

Police believe he was killed by a severe blow to the back of head as he walked home to Sutton-on-the-Forest from a party at the Star Inn, Huby, at about 11.30pm the night before.

Crimestoppers yesterday confirmed that the reward would be supplied for information on the case, which has so far baffled police.

Mr Williamson's grieving sister, Barbara Sherwood, has made two emotional appeals for witnesses to come forward but detectives have been disappointed with the response.
