(FILES) A picture taken on August 24, 2012 shows self-confessed mass murderer Anders Behring Breivik arriving in court room 250 at the central court Oslo to be sentenced for his twin attacks last year that left 77 people dead, bringing to a close one of the most spectacular trials in Norway's history. The Norwegian prison where Anders Behring Breivik is being held said on August 1, 2013 it agreed in principle to allow the convicted mass murderer to study political science, if the university wants him.
