A SEX offender who once tried to abduct boys outside a York school has been jailed after once again defying a court order.

Martin Kidd, 26, was imprisoned for 12 months by a judge at York Crown Court yesterday for breaching a Sexual Harm Prevention Order by accessing the internet at his workplace at York Railway Station.

The court heard he was prohibited from using the internet, apart from on his father's laptop which had appropriate software, but had admitted to probation officers he had done so on a workplace computer.

He exchanged messages on Twitter with a young woman who said she was 17, but then told her to block him so he wouldn't be tempted to contact her again.

He also used a chatroom to message a girl with a username which indicated she was 16, although she was actually 22, said Peter Yates, prosecuting.

Michael Rawlinson said in mitigation that he had been 'doing rather well' before he had been asked to use a workplace computer for an administrative task. "Temptation got the better of him," he said, calling for him to be given credit for his guilty plea.

Judge Andrew Stubbs QC said the order was intended to protect the public, particularly young girls, from his illegal attentions.

Kidd had not been able to resist temptation and had been sexually aroused by his conversations. "You cannot control your actions," he said, adding that he would have imposed an 18-month sentence but for his guilty plea.

Several judges have already spoken of their concerns in the past about Kidd.

In February 2012, as he was sentenced for trying to lure two 11-year-olds into his car, Judge Roger Ibbotson told him: "There is a very disturbing pattern to you committing offences with such persistence."

He jailed him for 16 months for two charges of attempted abduction of a child and made a five-year restraining order.

Within days of being released from that sentence, he broke the restraining order by texting a 14-year-old girl.

Recorder Graeme Cook, jailing him for four months, said: "Your behaviour is concerning to me."
