AN ARMY barracks cleaner was cleared of a knifepoint sex attack on a schoolgirl but immediately told by a judge that he faced jail for having child porn pictures.

Peter Robinson, aged 22, was acquitted of the attack on a 15-year-old girl who was pushed off her bike before her clothes were slit with a knife.

The alleged attack happened in May at Horseshoe Lake, Crowthorne.

But Robinson was ordered to sign the sex offenders' register and warned he could go to jail for possessing pornographic images of children on his computer.

Robinson earlier admitted possessing the indecent images after police found them the day they spoke to him about the allegation.

Judge Josh Lait, sitting at Reading Crown Court last Friday, ordered a psychiatric and pre-sentence report, along with a report from the sex offenders' programme, Thames Valley Police Project, before sentencing Robinson.

He said: "Jail must be a likely outcome."

Robinson was bailed until February, when he has been ordered to return to the court for sentencing.

The jury has heard how Robinson was accused of being the man wearing a grey hooded anorak and bright yellow waterproof trousers and smelling of urine who attacked the 15-year-old.

Robinson told the jury he had not left his home and watched television and phoned friends during the time he was alleged to have attacked the girl.

Robinson, of Kingsley Road, Eversley, was cleared of indecently assaulting the girl on May 3.
