A man has been jailed after he had sex with a 13-year-old schoolgirl.

Andrew Dallas prosecuting told Leeds Crown Court Robert Pratt, now 22, knew the girl’s age from when they were first introduced last year.

On one occasion they watched films together at a house along with other young people and a week later she began visiting his flat in Dewsbury Moor.

Things subsequently progressed to them kissing and cuddling on the sofa while watching a film and he suggested they have sex together.

Mr Dallas said a few days later Pratt and the girl again had sex this time at her home.

The offences came to light when another person told the girl’s mother. She challenged Pratt about that and forbade him seeing her daughter. In spite of that he continued to try and contact her on Facebook.

The court heard in 2010 Pratt was convicted of two offences of indecent exposure to an elderly woman.

Robin Frieze, representing Pratt, said he had not specifically targeted the girl but had been introduced by a mutual friend. He realised knowing her age there should have been no sexual contact between them.

Pratt of School Crescent, Dewsbury Moor, admitted sexual activity with a child and was jailed for two years 10 months. He was also ordered to register as a sex offender for life.

Recorder Caroline Wigin said he had known her age throughout.

“You had a significant disparity in age with this girl, you did indeed use grooming behaviour with her and after her mother told her to have nothing to do with you, you continued to try to contact her on Facebook inviting her to see you again.”
