An autistic man who contacted a 14-year-old Bracknell girl on Blackberry Messenger and persuaded her into hotel sex twice, has avoided jail.

Kalum Gilmour admitted that he had slept with the young teenager at a Hilton Hotel. 

He was able to contact the girl because one of her friends published her Blackberry PIN number online but his defence counsel said the 19-year-old was not targeting underage girls. 

The court heard how messages were exchanged between the pair from January 21 last year, before they started speaking on the phone over Facebook, and sending each other photographs. 

Prosecuting, Richard Moss told a judge how the teenagers discussed having intercourse together in detail.

Gilmour then travelled from his home in Torquay, South Devon, to Bracknell train station in February to meet the girl.

After spending time with her friends, he invited her back to his hotel where they had sex twice. 

Mr Moss said: "He met her in the station with two of her friends. They spent some time together and then she went to the hotel with him.

"He told her to say to hotel staff that she was his cousin if they asked," the prosecuter told Reading Crown Court.

"Things progressed in the room from kissing."

Thames Valley Police and social services were contacted after one of the schoolgirl's friends reported the incident to the authorities.

Defending, Alisdair Smith said Gilmour's severe autism left him immature compared with other older teenagers and that he had a low IQ of just 72.

He added Gilmour had the sexual interest of a 19-year-old male, but that he was immature compared with other people his age.

Giving the teenager a 16 month sentence in a young offenders institution, suspended for two years, Judge Paul Dugdale said: "When you spoke to her you were just making contact with other people. 

"She told you straight away she was 14 years old and you told her you were aged 19 years.

"You knew at 14 she was under the age of consent and you knew it was illegal to have sex with her. The reason this offence exists is because people who are aged 14 are not in a position of maturity to be able to give their consent to sex.

"Somebody who is 14 is a child."

Judge Dugdale determined that because of his immaturity and previous good character, an immediate custodial sentence was not appropriate. He also said the communication between them was "contact" rather than grooming.

He told the court it was also not appropriate for the 19-year-old to be put on a three-year sexual harm prevention course alongside other sex offenders.

Instead he said Gilmour would be subject to a similar programme on a one-to-one basis.

As way of punishment, the unemployed teenager was given a four month curfew from 8pm to 7am, at his parents' house.

He was also placed on the Sex Offenders' Register for 10 years.
