London, Feb 3 : Austrian incest fiend Josef Fritzl is to make a fortune by selling his "House of Horrors".

The 73-year-old could rake in more than a million pounds for the pad, as `sick' buyers will want to turn it into a museum.

Fritzl is selling the apartment from prison, reports the Daily Star.

The electric engineer is currently awaiting trial charged with rape, incest, kidnap, false imprisonment and slavery.

He repeatedly raped her daughter and fathered seven children with Elisabeth, now 42 - and took three of them to live with him and his wife Rosemarie, 70, in their home above the basement.

Three others were held captive with their mother, and Fritzl is also charged with murdering a baby, Michael, by failing to get medical help for the infant.

However, under Austrian law he is free to sell the home in Amstetten for an inflated price.

"It will be put up for sale after the trial," said mayor Herbert Katzengruber.

One insider said: "There is a massive interest in what went on here. Some people think they could turn the building into a money-spinner if they could get permission to open it to the public." (ANI)
