London, May 9 (ANI): Josef Fritzl dubbed the cellar, where he raped his daughter for 24 years and held her and three incest kids captives, as "my kingdom", a chilling jail confession by the sex beast revealed.

The maniac admitted that it was always his "dream" to cage his beloved Elisabeth without daylight and father a secret "second family" by her.

And he candidly told of his "joy and delight" as he made his nightmarish fantasy come true - with his wife never suspecting a thing as their daughter spent 24 years below ground being raped by him.

The depraved dad accused Elisabeth of being a tearaway and said he locked her away at the age of 18 for her own good.

"It was my dream to have another normal family - in the cellar - with her as a good wife and several children," The sun quoted him, as saying.

He told in savagely cold detail how he forced Elisabeth to bear him seven kids, terrorised his underground family into never trying to escape by claiming the dungeon's doors were rigged to electrocute them.

Fritzl said: "I was delighted about the children. It was great for me to have a second proper family in the cellar, with a 'wife' and a few children."

He told his lawyer Rudolf Mayer: "I always knew over 24 years what I did was not correct and that I must be mad to do something like this. Yet despite that, at the same time it just became a matter of course that I lived my second life in the cellar." (ANI)
