London, Nov 16 : Austrian incest fiend Josef Fritzl, who first raped his daughter Elisabeth when she was just 14, fears that he will be locked up in a psychiatric prison with a brain-eating cannibal who hates paedophiles.
The 73-year-old has been warned the Hannibal Lecter-style beast is after his blood.
Twisted Robert Ackermann - who killed his flatmate and gobbled his brains - flew into a rage when he heard about Fritzl's crimes.
Ackerman, who was 19 at the time, munched on the brains of Austrian-born Josef Schweiger, 49, for two days before the body was found by a cleaner at a hostel in Vienna.
Fritzl is now convinced that the German cannibal plans to turn him into Fritzl-schnitzel.
The dungeon dad kept Elisabeth chained up in a cellar as his sex slave for 24 years, fathering eight children by her.
Recently he was formally charged him with murder, rape, mental torture, slavery, incest and false imprisonment.
And they specifically recommended he should be locked away for life at Goellersdorf the country's high-security hospital for the criminally insane where Ackermann is an inmate.
Prisoners at the soft remand prison in St Poelten, where Fritzl is awaiting trial, have already begun taunting the petrified pervert.
"They used to bang on his cell and shout, 'Satan - come out and play.' Now they bang on his cell and shout, 'Ackermann is going to eat your brains'. Fritzl is terrified at the thought of ending up somewhere where Ackermann can get to him," the Daily Star quoted a warder, as saying.
Fritzl is due to stand trial in March. A psychiatric report declared he was responsible for his crimes but had a severe personality disorder.
