Unseen CCTV footage of Norwegian mass murderer Anders Behring Breivikhas emerged which shows him parking his van and walking off before an enormous bomb explosion took place. .
The security camera video from July 2011 captured the plotting of the explosive device in Oslo that weighed around a ton and killed seven people, as well as injured dozens of others.
Mass killer Breivik, in the footage is wearing a security guard's uniform who parks his white van at the entrance of a building that housed the Prime Minister's offices. He then quickly got out of the vehicle and walked away.
Later he gets into a second vehicle, a grey Fiat van, that he drove to the nearby island of Utoya where he gunned down 69 people, at a Labour Party youth camp.
Photographs of Breivik parking the van were released before, and the footage was shown during his trial earlier this year, but this is the first time the video has been released publicly.
It is part of a documentary that Norway's public broadcaster NRK will air on Tuesday evening.
