A 75-year-old paedophile has been convicted of sexually abusing a child 25 years ago.
Serial child abuser William McIntosh denied sexually assaulting the boy, who was a teenager at the time, and forced his victim to relive his ordeal in the witness box.
A jury at the High Court in Livingston took just over an hour to convict McIntosh of the crime against the youngster, which was the historic equivalent of rape.
The court heard that the accused befriended the youngster when he lived near Aberdeen.
On an occasion between June and October 1993 the teenager’s parents allowed him to stay over with the accused at the Rob Roy caravan park in Peterculter, Aberdeenshire, to help him carry out deliveries the following day.
McIntosh plied the youngster with alcohol and induced him to look at pornographic magazines before indecently assaulting him and forcing him to perform a sex act, the jury was told.
The prosecution led corroborating evidence that McIntosh, of Tomintoul, Ballindalloch, had abused a 10-year-old boy in the same caravan between October 1991 and July 1992.
The paedophile, who will be sentenced later, is already on the sex offenders’ register for life.
He has convictions dating back to 1980 when he held a 12-year-old boy in a shop and indecently assaulted him.
After being jailed at Peterhead Sheriff Court for 30 months he re-offended in 1987 and 1990.
He earned an eight-year stretch in 1998 for abusing four boys in Aberdeen and at the caravan park in Peterculter.
In 2007 a sheriff granted a sexual offences prevention order banning McIntosh from contact with children, apart from his own family.
It also barred him for going near play areas, school grounds or places where children might be present.
Following the jury’s majority verdict in Livingston, Judge Lord Woolman called for criminal justice social work reports and told McIntosh he would be sentenced at Edinburgh High Court on 26 March.
