Norwegian psycho Anders Behring Breivik is becoming even more extreme and dangerous in prison, according to his father.
Speaking for the first time since the crazed attacks that left 77 dead, Jens Breivik said he had requested to visit his son at the Oslo prison where he is serving a 21-year sentence.
But the right wing fanatic told him that he would have to a adopt a "fascist" ideology for them to have any contact in a letter.
Launching his book "My Fault" the elder Breivik said: "The letter scared me. I think he's becoming more and more extreme. Maybe he's becoming more dangerous too."
