A SUSPICIOUS wife uncovered her husband as a paedophile after she suspected he was having an affair.

Morwenna Clark was shocked to see her husband Andrew Clark, a former Chiltern District Council officer, was actually looking at child porn when she expected to find him contacting a lover by email.

Clark, 58, of Mulberry Close, Tring, was sentenced to three years in jail after admitting a string of serious sexual offences when he appeared at Aylesbury Crown Court on Monday.

Clark also indecently assaulted two young girls.

The court heard that Clark's wife spied him at his computer in September 2002.

Andrew Howarth, prosecuting, said: "She thought it might have been an accident. She watched him again and saw an image of young boys and girls naked."

Mrs Clark checked Clark's computer with a friend and found A4 pictures downloaded from the internet with sexual images of children and more than 30 CDs.

Clark's home was raided in December 2002, and despite attempts made to wipe the computer's hard drive, the police found enough evidence to charge him.

Last year police began investigating Clark after two women made complaints of sexual abuse when they were aged between nine and 13.

Tamla McGhee, defending, said Clark had indicated "total remorse and complete shame while there were no fits of violence and no evidence or distribution of the images".

The court heard Clark's marriage was heading for divorce and his relationship with his family had broken down.

Judge Roger Connor said: "All indecent assaults with children are serious and have long-term consequences by damaging their emotional development."

DC Deborah Lee, of Thames Valley Police CID, said: "It is important for the victims that they have closure. With this case it was not so much about the sentence, it was about the fact that he admitted what he had done."

Clark was convicted after admitting seven indecent assaults on the two girls, one charge of gross indecency with one girl and five counts of possessing and making indecent photographs of children. He will also go on the sex offenders register.

Clark was members and electoral manager at Chiltern District Council before resigning. He left in January.
