London, May 15 : Austrian incest dad Josef Fritzl enjoyed romps with teenage rent-boys and transsexual hookers in a Thai sex paradise, it has emerged.
According to sources, the 73-year-old monster sickened British holidaymakers after they spotted him hand-in-hand with a 16-year-old lad.
Fritzl stayed at the resort in Pattaya for up to six weeks at a time, trawling the notorious gay haunt Boyztown at night.
Brit Stephen Crickson, 51, of Huyton, Liverpool, said: "He was a disgusting pervert and all the ex-pats and regular holidaymakers knew what he was up to.
"Rent-boys, ladyboys, he would go with anything. At one point he was spotted by one bar regular with a 16-year-old," The Sun quoted Crickson, as adding.
British families suspected he was a German - not Austrian - because he would reserve sunloungers with a beach towel.
Stephen, at the resort with his girlfriend, added: "Fritzl would lord it around us at the beach and treated staff with contempt. He was universally unpopular."
