Norway police still probing if killer acted alone

OSLO - Norwegian police are still investigating whether an anti-immigration zealot who killed 77 people in central Oslo and on a nearby wooded island was acting alone or with others.
Anders Behring Breivik, 32, has been detained in solitary detention at a prison near the Norwegian capital after confessing to the killings, the most serious attack in the Nordic country since World War Two.
"We are still trying to clarify whether he was alone or not," police prosecutor Christian Hatlo told reporters on Tuesday.
No one else is currently under suspicion over the bombing in Oslo and shooting spree at Utoeya Island some 44 km away (28 miles) on July 22.
