Mass murderer Anders Breivik makes a Nazi salute as he begins lawsuit against Norway for 'violating his human rights' by keeping him in isolation - where he has a computer and a PlayStation

Norwegian mass murderer Anders Behring Breivik raised his right arm in a Nazi salute on Tuesday as he arrived for the first day of the lawsuit he is bringing against the Norwegian state to change the conditions of his detention. Breivik, 37, murdered 77 people and injured more than 300 - many of them teenagers - in July 2011, by detonating a bomb in downtown Oslo and carrying out a mass shooting on Utoya Island. Breivik claims he is a 'a victim of cruel and inhuman treatment' in Skien prison, 87 miles south-west of Oslo, where he has an entire cellblock to himself and access to a computer and a PlayStation.
