A judge has banned a teenage sex offender from speaking to girls in public places as part of an anti-social behaviour order.

Tristan Rabhi, 19, was told he could not start a conversation with any girl aged under 16, after he appeared in court for sentencing.

He had been warned by a judge last September that he was giving him a last chance when he sentenced him to a 50-week prison sentence, suspended for two years, for two counts of exposure and one of sexual assault.

However, within six weeks Rabhi, of Wissett Way, Lowestoft, grabbed hold of a 15-year-old girl's arm as she was walking home from school, the court heard. He had denied common assault on the girl, but was found guilty at Lowestoft Magistrates' Court during an earlier hearing.

On Wednesday, he was given a custodial sentence after appearing before Judge John Devaux at Ipswich Crown Court for being in breach of the suspended sentence. Judge Devaux ordered Rabhi to serve 40 weeks of the suspended sentence with 12 weeks to run consecutively for the common assault.

He also made Rabhi the subject of an indefinite anti-social behaviour order (Asbo) banning him from initiating conversations with any female under 16 in a public place, preventing him from entering any school for children under 16, apart from those attended by his own children, and preventing him from being in a house with anyone under 16, apart from his siblings or his own children, unless another adult was present.

Robert Sadd, prosecuting, said the offence of common assault was committed on November 2 last year when Rabhi had approached a 15-year-old girl as she walked home from school.

He said the girl saw Rabhi coming out of some bushes fiddling with the zip on his trousers and he'd asked for directions to a local sports centre. She had refused to show him where to go and he had replied: “Come on you gave me a cheeky smile earlier.”

Rabhi had then asked the girl to go round the corner with him and had taken hold of her arm. She managed to break free and Rabhi had walked off when one of the girl's friends approached.

Mr Sadd said that the offences of exposure for which Rabhi had received the suspended sentence related to him exposing himself to two 16-year-old girls in August 2006. The sexual assault offence related to him cycling up behind a 15-year-old girl and touching her between the legs over her clothing before riding off.

Helen Chapman, for Rabhi, said any physical touching of the 15-year-old victim of the common assault had been minimal and was not classed as a sex assault.

She added that he had been making good progress with the help of the probation service.

The court heard that Rabhi was not suffering from any mental illness.
