The Norwegian man charged with twin attacks that claimed at least 93 lives in Norway Friday had "lots of ammunition" in his possession when he was arrested, police said Sunday.
Oslo police chief Sveinung Sponheim told reporters the accused had two guns on him when he surrendered to special police forces, dpa reported.
The police arrived on Utoya island near Oslo one hour after local police received an emergency call about shootings, Sponheim said.
The shooting spree has claimed at least 86 lives. Sponheim said police had not been able to establish how many people were on the island at the time of the attack.
Published reports have mentioned a tally of some 500.
The accused - named by Norwegian media as Anders Behring Breivik - has also been charged with a bombing hours earlier in central Oslo that killed seven people.
