A SEX offender who preys on teenage boys has been warned he faces many years in jail if he doesn't stop "chatting up young men in the street."

Nigel Delaney, 63, appeared in custody at Bradford Crown Court to plead guilty to breach of a Sexual Offences Prevention order and sexually assaulting a 16-year-old boy.

Delaney bought the youngster tobacco, a burger and soft drinks and told him he could make "big money".

He approached the college student in Keighley on April 24, prosecutor Peter Hampton said.

Delaney, of no fixed address, bought him tobacco and the pair went to Jack and Danny's pub on Church Green, Keighley, and played pool.

Mr Hampton said Delaney asked the student if he would provide sexual services to a woman aged 50 and told the youngster he hated paedophiles, while touching and patting his leg.

He said the boy could make "big money" and asked him if he had ever had gay sex, the court was told.

He gave him £5 and said he would be in the pub that evening.

The boy told the police and Delaney was arrested.

Two years earlier Delaney, then of Emsley Close, Bierley, Bradford, was jailed for 18 months for sexually assaulting a 15-year-old boy he targeted at a gym.

At the time he was already subject to a Sexual Offences Prevention Order imposed in 2009 when he received a suspended jail sentence for two charges of harassing teenage boys by sending them lewd text messages.

Yesterday, Judge Jonathan Durham Hall QC made a Sexual Harm Prevention Order and sentenced Delaney to 12 months imprisonment, suspended for two years. He must register with the police as a sex offender within three days or risk going back to jail.

The judge told him: "If you come back, the book will be thrown at you."
