A lesbian couple in Australia face 15 years imprisonment for murdering a British teenager because she irritated them, according to The Sun.

Jessica Stasinowsky, 20, and Valerie Parashumti, 19, confessed to beating 16-year-old Stacey Mitchell to death with a concrete block before dumping her body in a wheelie bin.

She was found by police in a shed after her parents had reported her missing in December last year.

Ms Mitchell, whose family had emigrated from West Moors, Dorset, was staying with the couple.

The pair, who admitted that they had thought about hacking Ms Mitchel up with a chainsaw, will appear in court in Perth, Western Australia next month.
