Woman, 36, jailed for sex with boy, 12

Angela Sullivan, 36, even gave the boy a pair of trainers as a reward after he slept with her for the 100th time.

When police arrested her in October, they found her diary marked with childish entries, and 191 stars against dates when they had sex.

The unemployed single mother, of Cavendish Road, Middlesbrough, admitted 10 specimen charges – relating to one sex session for each month of their fling last year – of causing or inciting a child to engage in sexual activity.

Richard Bennett, prosecuting, told Teesside Crown Court that the abuse started on the night of a party she threw at her home in January last year.

The boy, who cannot be named for legal reasons, later told police he had consumed 10 bottles of a vodka-based drink.

"The defendant took the intoxicated boy up to bed," Mr Bennett said. "There is no doubt that at the time she knew he was only 12 years of age when she placed him on her own son's bed."

Jailing Sullivan for nine years, Judge John Walford described the case as "shocking".

"You took advantage of this boy's age," the judge said.
