Vienna - Josef Fritzl, the Austrian accused of having raped and imprisoned his daughter, has said he also kept his mother locked up in his house, Austrian media reported Thursday.
According to members of his family, Fritzl, 73, frequently insulted his mother and locked her up in a room in his house, where she died in 1980. He also bricked up the room's window, News magazine reported.
