Josef Fritzl 'makes killer pal in jail'

London, Mar 19 : Jailed Josef Fritzl, the Austrian man who imprisoned his sex slave daughter in a secret dungeon for 24 years, has found a pal in a killer who slaughtered seven people.

Fritzl, 74, is caged in the maximum security Stein jail in Krems, Austria, where Harald Sassak has also been incarcerated.

They are both serving life sentences and according to sources they have become close pals, reports The Sun.

Fritzl was convicted of killing one of the seven children he fathered by daughter Elisabeth.

As far as Sassak is concerned, he was Austria''s most notorious killer and was known as ''The Gasman'' because he posed as the employee of an energy firm. He throttled seven pensioners — raping one of them — before ransacking their homes for cash and jewellery.

Besides Sassak, Fritzl has also become friends with triple killer Guenter Lorenz and former Olympic skater Wolfgang Schwarz who trafficked young girls into prostitution.

A prison officer said: "They are quite a grim little gang.

"No one is in here because they''re an angel but this lot are the dregs of the world."

While talking about Fritzl, prison general lieutenant Peter Prechtl said: "He is unobtrusive and has adapted well to day-to-day schedules."
