London, Nov 16 : Austrian incest fiend Josef Fritzl wanted to make the windowless dungeon a tourist attraction where he imprisoned his daughter and fathered seven children by her, according to reports.
According to reports, the 73-year-old wanted to charge visitors to enter his former home in the town of Amstetten in a bid to raise money for his traumatised family.
Fritzl's plans were revealed by his sister-in-law, named only as Christine R, in an interview with the Austrian tabloid Oesterreich on Saturday.
"He actually wanted to make a tourist attraction out of his house with the dungeon where he kept Elisabeth, and charge ten euros for entrance," the Telegraph quoted her, as saying.
"It is completely mad. The family was supposed to get the proceeds, but, naturally, all of them rejected his 'business' proposal," she added.
Fritzl has confessed to imprisoning and sexually abusing his daughter Elisabeth, 42, in a rat-infested, windowless subterranean bunker beneath his home, where she gave birth to seven of his children.
Recently he was charged with murdering one of the children he fathered by his daughter.
Prosecutors say he is responsible for his son's death as he failed to get proper medical attention when the baby fell ill shortly after birth.
Fritzl is due to stand trial in March. A psychiatric report declared he was responsible for his crimes but had a severe personality disorder.
