Police in the Lower Austrian town of Amstetten have arrested a 73 year old man who is alleged to have kept his daughter, now aged 42, locked in the cellar of his house in Amstetten since 29th August 1984. The man, identified by police as Josef Fritzl, is alleged to have started sexually abusing his daughter, named as Elisabeth Fritzl, when she was eleven years old, and to have subsequently fathered seven children by her. One of the children, one of a set of twins born in 1996, died of neglect shortly after birth and the body was burned by the father.
