A recording of the first call of Anders Behring Breivik (photo, from bbcimg.co.uk) to the police was broadcast by Norwegian commercial TV channel TV 2 for the first time on Tuesday.
Norwegians have heard the self-confessed mass killer introduce himself as a “Norwegian anti-communist resistance commander” and say he wants to surrender.
But when the police asked him to give his number he hung up and resumed shooting people at a youth summer camp in Utoya island, near the country’s capital.
People affected by the attack would not have been “very happy to hear his voice broadcast into their living rooms”, lawyer John Christian Elden, who represents Breivik victims, told TV 2.
Geir Lippestad, Mr Breivik’s lawyer, said it was difficult to understand why his client had continued shooting after offering to surrender in the first call.
Mr Breivik has admitted that on 22 July, disguised as a police officer, he planted a car bomb which exploded close to government offices in Oslo, killing eight people. Then he drove to the youth summer camp on the island of Utoeya and shot dead 69 people, most of them teenagers.
He made his calls to emergency services from the island. During the first call which lasted only a few seconds at 18:00 local time, he gave his name and said he is calling from Utoeya and wants to surrender, but without any explanation.
He called back at 18:26 to say he has completed his “operation” and wants to surrender. Only a transcript of that call is available.
On that day Mr Breivik killed 77 people and injured 151 in the attacks which he described as “necessary” for the salvation of Norway and Europe from Muslims and multiculturalism.
Traumatised by the carnage, Norway marked the attacks with a month of mourning and a national memorial service.
Anders Behring Breivik is scheduled to go on trial on 16 April, pending psychiatric tests.
