A man raped a teenager on her 18th birthday and sexually abused two young girls.

Peter Watson, of Alloa, Clackmannanshire, has been jailed for eight years and three months following the attacks.

The 69-year-old carried out the rape almost 40 years ago, while the sex abuse was more than 20 years ago.

Judge Lady Rae said: "This is an appalling catalogue of crime. You raped a young woman on her 18th birthday and some years later you went on to seriously abuse young children.

"Such offences could have a life-changing impact on children and a young woman. It beggars belief what you have done."

Prosecutor Lynsey MacDonald told the High Court in Glasgow: "The rape took place in 1978 when the accused was 30.

"The complainer went out with friends to celebrate her birthday. She ended up back at the accused's house and fell asleep, fully dressed, on the couch in the living room.

"During the night the accused came into the room and removed her trousers and underwear. She woke up disorientated and confused."

She added: "The woman had never previously had sexual intercourse with anyone. She did not tell anyone what had happened."

Years later she met another of his victims at a wedding who told of how Watson had abused her.

The other woman, who is now 49, then went to the police.

She told officers she had been indecently assaulted by Watson on one occasion when he was babysitting her.

Another victim came forward to say Watson indecently assaulted her when she was between nine and 14 while looking after her.

Watson, a first offender, admitted the sexual abuse offence, committed between 1982 and 1992.

The rape was committed in 1978. All the offences took place at addresses in Stirlingshire.

Watson was placed on the sex offenders register. He showed no emotion as he was led away to begin his sentence.
