A PARK South man made vile comments about a 13-year-old girl’s appearance and told her to text him if she wanted sex.

The girl, who was being driven by Martin Williams at the time, was left extremely uncomfortable and tried to change the subject.

But one-track-mind Williams – who was more than 30 years her senior – kept up his perverted commentary, even after he’d parked up the car near South Cerney to relieve himself.

Prosecutor James Tucker told Swindon Crown Court this morning that Williams, 48, was driving the young girl.

He began talking about her appearance, telling her she was “really fit and pretty” and had “big boobs”.

Williams said he could imagine having sex with the girl: “If I was younger I would s*** you. I’m deadly serious.” Mr Tucker said the older man added: “If you do want to do it just give me a text.”

He urged the teenager not to report their conversation. “You can’t tell anyone,” he was reported saying. “You can’t even tell your mum or dad else my daughter would be taken off me.”

The girl’s mum later found out about the conversation and the matter was reported to the police.

Jailing him for two-and-a-half years on Thursday morning, Judge Jason Taylor QC said: “What happened in this case is best described as grooming conversation where you were laying the groundwork for future penetrative sex as opposed to that day. That, of course, doesn’t minimise the fear that your victim experienced.”

He added: “This incident may have been relatively, and I emphasise the word relatively, short lived but it will remain with her for far longer - possibly her life - and this court must reflect that.”

Williams, of Leighton Avenue, Park South, pleaded guilty at an earlier hearing to inciting a child to engage in sexual activity and sexual communication with a child. He had no previous convictions for sexual offending.

Rob Ross, mitigating, said his client was suffering from post-traumatic stress disorder. As a young man he had witnessed his mother die in front of him and was also present at the Akers Way tragedy in 1991 when five young people – including his close friends - lost their lives to a speeding motorist.

The solicitor said material collected by the police shortly after the incident showed Williams had “realised the stupidity of what he’d done very soon afterwards”. He was a council house tenant and in employment. A number of references had been provided.

The judge said he had taken Williams’ mental health disorder into account when sentencing him. Even if the 30 month jail sentence had been in the range where it could be suspended, he would have imposed immediate custody, Judge Taylor said.

Williams must abide by a sexual harm prevention order and register as a sex offender for life. A three-year restraining order prevents him from contacting his victim.
