London, Aug 20 : Dungeon girl Kerstin Fritzl ripped out handfuls of her hair in frustration during her cellar ordeal, it has emerged.

Shocking details of the torment of incest dad Josef Fritzl’s cellar children have emerged for the first time. It has been revealed that they ripped out their hair, tore off their clothes and blocked their dungeon toilet in a bid to show their mental torture.

And at least one still walks with a back-breaking stoop from almost two decades of being unable to stand upright.

London, Aug 8 : Austrian incest fiend Josef Fritzl lied that he rigged the cellar door to open if he died, it has emerged.

This revelation implies that his daughter and the kids she bore him would have been entombed forever.

Fritzl, 73, had told police that the 50-stone mass of steel and concrete had a timer, which would automatically open if he did not reset it.

He claimed it ensured his secret brood would be freed if he failed to visit them, reports The Sun.

London, Aug 7 : Austrian incest fiend Josef Fritzl''s crimes may never be known to the public because his trial will be heard in secret, it has emerged.

Daughter Elisabeth, 42, will testify against 73-year-old Fritzl behind closed doors to protect the six surviving children she bore him.

Elisabeth, who was imprisoned as a sex slave for 24 years below the family home, has already given a full statement to Austrian prosecutors about her ordeal, but her children have not, reports the Mirror.

Prosecutors are investigating whether it is possible to spare them the ordeal and if Elisabeth''s testimony is enough to lock up her father for the rest of his life.

London, Aug 5: Austrian incest fiend Josef Fritzl may be charged with slavery and murder, say prosecutors.

Prosecutors hope to formally charge Fritzl in September and put him on trial in December.

According to investigators, the 73-year-old has confessed to locking up daughter Elisabeth, 42, for 24 years, raping her and fathering her seven kids.

Fritzl can face a murder charge if it can be proved that one infant, who died just after birth, would have survived if it had got medical treatment. He may be locked up for 20 years.

London, Aug 4 : Dungeon dad Josef Fritzl’s son Felix, 6, is making miraculous progress after his horrific ordeal in the cellar, and can even ride a bike and swim.

According to reports, Felix rides his bicycle in the grounds of the Austrian hospital where he was taken along with his mother and other five siblings after being rescued by the police on April 26.

Now, the doctors have taught him various skills while he gradually re-adjusts to life after the dark years he was forced to spend in the cellar.

“They have been amazed at how Felix is adapting. He is really cheerful and fascinated by everything,” News of the World quoted an hospital insider as saying.

London, Aug 4 : Austrian prosecutors are mulling over whether to charge Dungeon dad Josef Fritzl, 73, with slavery to maximise the time he serves in jail.

Fritzl has admitted to having imprisoned his daughter Elisabeth for 24 years in a secret cellar beneath his home in Amstetten, where he fathered six children with her.

While he kept three of the incest children with him and his wife Rosemarie, 68, in their upstairs apartment, the other three lived with Elisabeth in the concrete bunker until police rescued them on April 26.
