Prosecutor fears Breivik is holding back on accomplices

A prosecutor says the man who killed 77 people in Norway on 22 July is refusing to give information that would help the authorities determine if he had accomplices.

Anders Breivik has confessed to the shooting massacre at a youth camp, in which 69 people died, and the car bombing hours earlier in Oslo's government quarter that killed eight.

"We still think he was alone, but we cannot conclude about that. He holds back information, and that worries us," said prosecutor Christian Hatlo.
