Sean Moynihan targeted the 18 year-old with a knife in broad daylight as she walked along a cycle track in Johnstone, last October.

Armed with a “rape kit” - including a six-inch blade and condoms – he ordered his victim to strip before forcing her into sex.

The young woman told a jury how she was left a “mess” after her harrowing ordeal.

She recalled initially seeing Moynihan in front of her. The teenager thought he was stopping for a rest while out jogging.

Moynihan – who also wanted money and ordered the young woman to be quiet – forced her further into an area full of stinging nettles.

The victim then remembered Moynihan “aggressively” telling her to strip naked.

She told the trial: “I was crying as I started taking my clothes off. I was saying: 'why are you doing this?' “He said: 'Don't ask silly questions or I will stab you.” Moynihan insisted to detectives the sex had been consensual – and even claimed the victim had happily chatted about her family and an ex-lover.

But, in a bid to back-up his sick lies, police believe the 30 year-old scoured her Facebook page after the attack to glean personal information about her.

Moynihan now faces life in jail after being found guilty at the High Court in Glasgow of the sex attack.
