London, Aug 7 (IANS) A woman and her boyfriend in Britain were jailed for punishing a teenage girl by raping her after they mistakenly thought she had stolen 100 pounds from them, Daily Mail reported Tuesday.

Elizabeth Seagrove, 40, was jailed for 12 years and six months and Matthew Costello, 31, was jailed for nine years and four months.

They denied carrying out the attack Oct 30, 2011, near Amersham, Buckinghamshire.

The pair drove their terrified victim around for more than an hour in the night in her dressing gown, to find a secluded place.

Seagrove then ordered her to strip and held her hair as she instructed her reluctant Costello to violate the 18-year-old.

It was only later, on returning home, that the duo realised it was someone else who had taken the missing money from them.

Judge Francis Sheridan described the attack as unspeakable and praised the victim's family and the police for their efforts in securing convictions of the woman and her boyfriend.
