Josef Fritzl, the Austrian man who is serving life after he confessed to keeping his daughter Elisabeth as a sex slave in a dungeon, has had two prisoners transferred after he became convinced they were plotting to kill him, it has emerged.

The Daily Star reports, a former inmate at Austria's Stein prison said: "Fritzl is always scared. Two people were even relocated because of him."

Meanwhile, it was last month reported that Fritzl, 74, who kept Elisabeth beneath the family home in Amstetten, Austria, sends a pleading note to her every two weeks.

From his jail cell, he has asked for forgiveness, 4,000 pounds to start a legal career and special shampoo for his implanted hair. (ANI)
