A married maths teacher has been placed on the sex offenders' register for having sex with a 16-year-old girl in the UK. Andrew Welsh (36) was caught by the girl's mother who found him hiding under the teenager's bed.

Bolton Crown Court heard he was caught when the the girl's mother returned home unexpectedly one morning last July. Geoff Whelan, prosecuting, told the jury the girl had ruffled hair and smudged lipstick.

When the mother went upstairs, she noticed a pair of men's boots at the side of the girl's bed, he added.

This "understandably aroused suspicion" in the mother, who asked the girl "What are you doing? Who is here?".

Mr Whelan continued "However, as that was said, she looked down and saw movement in the drawer compartment within the girl's single divan bed and the valance sheet folded back.

"She saw movement of material which seemed to match the suit jacket her daughter was holding. The girl replied 'Mr Welsh'. Her mother ordered the defendant to get out from under the bed and recognised him from the school".

The shocked mother called her husband and the police and Welsh was arrested. The court heard Mr. Welsh had begun a relationship with the "impressionable" girl last summer while she was taking her GCSE exams.

The St Andrews University graduate bombarded the girl with obscene texts, including "Have you heard about my maths lesson? We're going to find out if 35 goes into 16".

The father-of-one, who is married to a local doctor, admitted six counts of sexual activity with a child while in a position of trust.

He was given a 14-month jail term, suspended for two years, and ordered to carry out 200 hours of community service. He was also ordered to sign the sex offenders' register for 10 years.
