A driving instructor was today found guilty of a string of child sex offences.

David Aston, 32, of Bell Close, Cassington, denied sexual activity with a child, causing or enticing children to engage in sexual activity and making indecent photos of children.

But a jury at Oxford Crown Court has found Aston guilty of two counts of sexual activity with a child and and four charges of causing or enticing children to engage in sexual activity.

He was cleared of five counts of making indecent images of children.

Aston, a married father-of-two, had admitted driving four teenagers to secluded woodland, near Bicester, and asking them to kick him in the groin for sexual gratification.
