Incident Summary:

07/22/2011: On Friday afternoon, in Hole, Buskerud County, Norway, in one of two related attacks, a man identified as Anders Breivik and dressed as a police officer, rode a ferry from the city to the island of Utoya, which is the location of a youth camp that is run by Norway's ruling Labor Party. He told the ferry driver that he needed to go to the island and check that everything was secure because of the bombing that just took place in the city. Once on the island, Breivik identified himself as a police officer and then opened fire on the camp attendees with his semi-automatic, 5.56 caliber Ruger Mini-14 rifle and a 9 millimeter Glock pistol. Due to the camp's location on the remote island, Breivik was able to kill 69 people and injure at least 60 others, including teenagers, before the police could reach the scene. The attack caused an unknown amount of property damage to the camp. Once the police arrived Breivik surrendered without a fight and was taken into custody. Breivik confessed to the attacks and in August 2012 he was sentenced to 21 years in prison.
