London, Mar 16 : Jail officials have been keeping a close watch on dungeon dad Josef Fritzl to ensure that he does not commit suicide before his trial begins.
The 73-year-old Austrian held his daughter Elisabeth captive in a dungeon beneath his home, raped her since she was 18 years of age, and fathered seven children with her, while keeping her as a sex slave for 24 years.
Amidst tight security and huge media and public interest, Fritzl will appear in the dock in St Polten, around 40 miles east of his hometown of Amstetten.
