Vienna: 

Lunatic: Josef Fritzl

Josef Fritzl is terrified of his upcoming trial after learning that if convicted he would have to serve his sentence in a high-security mental asylum.

His jail mates will include cannibal killer Robert Ackermann, whose last victim was also a sex pervert.

One warder at the St Poelten jail, where Fritzl is currently held, said, "People in here for anything involving abusing children always get a hard time from inmates. "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'."
