Notorious Austrian sex monster Josef Fritzl has bragged about imprisoning and torturing his daughter in a new tell-all book.
Fritzl imprisoned his daughter Elisabeth when she was 18 years old, in a dungeon he built under his house, telling his wife and police that she had run away to join a cult.
The case only emerged in 2008 when she told police during a trip to hospital, in the town of Amstetten, Austria, that she had been held captive for 24 years by her father.
