When male stripper Paul Mansfield set himself as a ''naked butler'' serving champagne and shorts at hen parties in Blackpool, he was only too happy to brag about it on Facebook.

The bodybuilder who nicknamed himself ''PJ'' was regularly pictured on the social media site dressed only in a black bow tie and underpants.

He also posted a picture of himself flexing his muscles with the message: ''Buff butler for hen parties and birthday parties for all u ladies out there. U want to let ya hair down on a night out book in and u cud get this if u request it wen ya book a room.'

But unbeknown to colleagues and clients, 28-year old Mansfield was a sex fiend dubbed the ''Vampire rapist'' who bit his victims whilst prowling the Lancashire seaside resort.

One woman on a night out was subjected to savage attack in which Mansfield bit her neck as he raped her. Although he was arrested he was freed on bail and just weeks later attacked a second victim who was on holiday in the resort from her home in Glasgow.

The Scots woman who had become separated from her boyfriend during an evening out was dragged down an alleyway before being molested and bitten on her chest before being robbed of her handbag.

At Preston Crown Court, Mansfield was jailed for 13 years and branded a ''dangerous offender'' by police after he was convicted of rape and attempted rape and an unrelated offence of possession of crack cocaine with intent to supply.

Cavendish Press' coverage of the case went in the The Sun and on various newspaper websites. If you have a story please email [email protected].
