London, Jan 25 : Josef Fritzl, the Austrian incest fiend who locked up his daughter in a dungeon for 24 years and raped her more than 3,000 times, is terrified that a vigilante will attack him at his forthcoming trial, according to reports.
The 73-year-old beast, who is currently in custody at Austria's St Poelten prison, has reportedly asked for extra security for the court case.
Fritzl apparently realised the danger he was in after reading death threats sent to his legal team, reports the Daily Star.
