A FREED thug helped kidnap and torture an innocent teenage boy – just a week after he was released early from jail.

Christopher Rennie teamed up with Anthony Wright to pounce on the 14-year-old who had gone to his local shop for sweets and crisps.

The terrified child was grabbed off the street and hurled into a flat in Renfrew in January this year.

The hour-long ordeal saw him blindfolded, battered and robbed while one of the thugs told him: “I’ve killed before.”

They demanded he return home and steal £500 from his mum.

But, the blood-soaked boy managed to escape their clutches – despite being forced to walk in women’s boots.

Rennie, 27, and Wright, 23, are now behind bars after they were both convicted of abduction, assault and robbery.

It emerged after the verdicts that serial criminal Rennie was just back on the streets when he struck.

He was jailed for 40 months in September 2016 after car-jacking a woman at a supermarket.

But, he was freed on January 19 this year – less than halfway through the sentence and exactly a week before attacking the boy.

Jurors at the High Court in Glasgow heard the boy luckily escaped any major injuries, but did suffer a number of cuts and bruises.

Prosecutors said it was a “stroke of good fortune” he was not more badly hurt.

Judge Graeme Buchanan remanded the pair in custody as sentencing was deferred for reports.
