Norwegian police say the man behind the attacks that killed 77 people hung up twice on authorities while calling to surrender during the shooting at a youth camp at Utoya island.

The first phone call came 26 minutes before the police arrested Anders Behring Breivik, who identified himself as the commander in an anti-communist resistance movement.

Officers said that Breivik hung up and authorities unsuccessfully tried to call him back. Breivik called again one minute before he was captured, but hung up again.

Breivik detonated a car bomb outside government buildings in Oslo, killing eight, and then shot dead 69 others at a youth camp outside Oslo.
