A DEPRAVED personal trainer raped a teenager at knifepoint - after being freed from jail for another brutal sex attack.

Sean Moynihan pounced on the 18- year-old in broad daylight as she walked along a cycle track in Johnstone, Renfrewshire, 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 girl told a jury how she was left a "mess" after her harrowing ordeal. 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. He was back on the streets after being locked up for more than six years in 2009 for raping another teenage girl.

Moynihan was also apparently under supervision at the time and was already on the sex offenders list indefinitely. Other crimes to his name include a further high conviction for assault and a string of violent offences.

A judge branded him a "very dangerous young man" as sentencing was deferred until September.

Moynihan is believed to have been working as a personal trainer after being freed from jail. He was jailed at the high court in 2009 after raping a 16 year-old girl, who thought his car was a taxi. He drove her to Gleniffer Braes in Paisley before forcing the teenager to have sex. He was also ordered to be supervised for a further three years on his release.

After this latest conviction, Judge Bill Dunlop told Moynihan: "You have been convicted of rape for the second time.

"The nature of this offence shows beyond doubt that you are a very, very dangerous young man.

"The degree of planning to avoid detection can only be described as chilling."

Prosecutor Alison Di Rollo moved for a full risk assessment to be carried out on Moynihan prior to sentencing later this year. This could eventually lead to an Order for Lifelong Restriction being imposed meaning Moynihan may never be freed.
