Melbourne, May 5 : Austrian incest dad Josef Fritzl, who admitted to imprisoning his daughter and fathering children by her, has been transferred to solitary confinement, following death threats from his fellow inmates.

According to a report in UK's Daily Express Fritzl's cellmate in Austrian prison threatened to kill him when he learned of his alleged crimes.

The 63-year-old former bank robber allegedly flew into a rage when he discovered that Fritzl repeatedly abused and raped his daughter for 24 years.

“Child abusers are hated in Austrian prisons,” News. com. au quoted the cellmate, as saying.

“I know that if somebody has been blacklisted there is always a way of getting to him even if he is in solitary confinement.

“It can be during walks in the yard or during personal hygiene, or even at dinner which is prepared and served by the inmates,” he added.

Meanwhile Fritzl is still on suicide watch and his lawyer said he remained “distraught”.

“He is very depressed. It is certainly hard for him in jail," Dr Rudolf Mayer said.

“He is also very worried about all the threats. He was with another inmate but now he is on his own. He has a window and, as a remand prisoner, he has advantages over others,” he added.

According to Austrian police, Fritzl imprisoned his daughter, Elisabeth, in a soundproof, windowless dungeon in his basement for 24 years, where he fathered seven children by her. (ANI)
