Incest Father from Austria; Pictured on Boys Holiday

They come as it was revealed that Fritzl has told police he acted alone.

He has told detectives he was not helped to keep his Elisabeth and their children hidden in his cramped basement.

But police are not yet convinced he is telling the truth and are investigating how he could have bought food and clothes for them without anyone suspecting.

The 73-year-old pensioner, who has now been confirmed as the father of all Elisabeth’s children, was today remanded in custody for two weeks.

At a press conference in Austria after the brief hearing, police said: “He is saying that he worked alone, that he acted alone, in making sure his daughter was kept in that cellar but the authorities are not sure that is what happened.

“As a result they are now carrying out further inquiries. They want to know where the food came from to look after those children and where the clothes came from.”
