Norwegian gunman Anders Behring Breivik put down his weapons and surrendered without a fight following his shooting rampage on Utoya island, one of the first officers on the scene said Wednesday.

Havard Gasbakk, who was supposed to be having a day off last Friday, described scenes of shock and horror on the island, with the sound of gunshots coming “thick and fast.”

The group of eight police headed to the southern part of the holiday island, and began to call out. When they came across Breivik in a clearing, he placed his hands above his heads in a “completely normal” manner for an arrest, Gasbakk said.

Breivik’s weapons lay 50 feet (15 meters) away on the ground.

One of the unit detained him, while the other officers began tending to the many injured, who emerged continuously as though they were “on a conveyor belt,” the officer said.

Norwegian police say 68 people, including many youngsters, were killed in the shooting, hours after Breivik detonated a huge bomb in downtown Oslo.

Meanwhile, a Polish businessman faces up to eight years in prison after being charged for selling chemicals to Breivik, Norway’s Dagbladet newspaper reported Wednesday.

Lukasz Mikus, 32, was charged with public security offenses and faces between six months and eight years in prison, a Polish prosecutor told the newspaper.

Breivik named Mikus’s online trading business, based in the southern city of Wroclaw, in his “manifesto” detailing his preparations for last Friday’s attack, in which 76 people were killed in a bomb blast in Oslo and shooting at a youth camp on Utoya island.

Mikus told the newspaper that he had no idea that Breivik intended to use his chemicals in a bomb. He described the situation as “a nightmare.”

Polish authorities denied reports Monday that it arrested Mikus. But the businessman told the newspaper that he was questioned through Sunday night and Monday after armed police raided his home.
