'British Fritzl' kept 15-year-old as his sex slave

London, Mar 22 (ANI): A 36-year-old man, dubbed the "English Fritzl", chained a 15-year-old schoolgirl to his caravan and kept her as his personal sex slave, it has emerged.

Scrap dealer David Cooper even forced her to take part in orgies.

He put the girl through a four-month ordeal of abuse as her mum searched for her.

Cooper forced the teenage girl to indulge in group sex with him, his girlfriend Kerry Hobson, 28, and another man, then watched as his lover shaved off the schoolgirl's pubic hair.

It was when the teen tried to flee that he tied her to a concrete block beside his gipsy caravan with a motorbike chain.

Her ordeal ended when police raided the van on a remote site near Bridlington, East Yorks, looking for drugs and found the girl.

Cooper now has been jailed for nine years at Hull Crown Court after admitting eight specimen charges of sexual activity with a girl under 16 and one of child cruelty.

Hobson was jailed for three-and-a-half years, reports The Daily Star.

Passing sentence, Judge Michael Mettyear told Cooper: "You treated this girl like your own personal sex toy."

Last night the girl's mum said: "He is an English Josef Fritzl - every parent's worst nightmare."

The case draws similarity to Fritzl case, where the Austrian man caged his daughter in a rat-infested dungeon for 24 years and fathered seven children by her, six of whom survived.

Josef is now in jail serving life sentence. (ANI)
