DETECTIVES trying to solve the murder of a Fife man over seven years ago last night made a new appeal for help.

The BBC TV programme Crimewatch featured the killing of 33-year-old bachelor Sandy Drummond and highlighted information not revealed until now.

Mr Drummond was found strangled on a farm track near his home at Falside Farm, Boarhills, a few miles from St Andrews, on June 24, 1991.

Last night, in a reconstruction of events leading up to the time of Mr Drummond's death, the programme revealed for the first time the make of an orange-coloured car that had been seen parked near his home several times - including the day he died. It has been identified as a Morris Marina.

The reconstruction also disclosed for the first time that the police are anxious to trace a young man who boarded a service bus near Falside Farm on the afternoon of June 24 and was dropped off at Lamont Drive, St Andrews. He was carrying a handkerchief which appeared to be bloodstained.

Detective Chief Inspector Douglas Potter appealed to viewers who knew anyone who might have had an orange Morris Marina at the time to get in touch with police in Fife. He also asked the bus passenger to come forward.

Mr Drummond had worked at a Fife paper mill for seven years until suddenly quitting days before the murder. He drew a large amount from a savings account, but most of it was found in his home.

His brother, James, with whom he lived, said on the Crimewatch programme: ''Of all the people in the world he would be the last one that you would think would get murdered.''

DCI Potter said: ''I think it is very possible that somebody could have been bullying him or blackmailing him.''

Minutes after the appeal was screened, it was announced that calls to a special telephone number opened for the Fife case were already being received.
