Anders Behring Breivik's phone call to police made public. guardian.co.uk

A recording of a call made by Anders Behring Breivik to Norwegian police in which he offers to surrender after shooting a number of people on Utøya island has been released.

The audio clip is the first time the public have been able to hear the voice of the rightwing fundamentalist, who killed eight people in a bomb attack in Oslo before going on to shoot dead 69 more on Utøya on 22 July.

The 32-year-old introduces himself as "Commander Anders Breivik of the Norwegian anti-communist resistance movement". He tells the emergency operator he wants to give himself up but hangs up after being pressed for his mobile number.

After resuming shooting for 20 minutes he makes a second call, telling police: "I completed my operation … so I want to … surrender." He claims to be a member of the Knights Templar in the call, which is only available as a transcript.

Geir Lippestad, the lawyer representing Breivik, told the Norwegian television station TV2, which obtained the recording, that it raised questions about his client's state of mind.

He said: "It is difficult to understand why he did not put down the gun when he thought he had done enough damage."

John Christian Elden, the lawyer representing Breivik's victims, said the recording would be an unwelcome reminder for them. "They are not very happy to hear his voice broadcast into their living rooms, especially those who were at the island and heard him shout," he said.

Breivik made the call about 50 minutes after arriving on Utøya island where, disguised as a police officer, he opened fire on a Labour Party youth camp.

He has said he tried to call police at least 10 times during the Utøya attack but only got through twice.

Breivik killed 77 people in total in the shootings and bomb attacks before surrendering to a police Swat team.
