A victim who was shot during the attack on the island told CNN Saturday that he had seen pictures of Breivik taken from what is believed to be his Facebook page and shown on television stations NRK and TV2. The victim said he recognized the man from news reports as the gunmen.
That attack and the massive explosion that targeted government buildings in the heart of Oslo are linked, police said.
Seven were killed and nine were badly wounded in the explosion, Frykholm said. In all, 90 people were hospitalized as a result of the blast, said Erik Hansen, a spokesman for Oslo Mayor Fabian Stang.
It was while authorities were searching for survivors of the mid-afternoon bombing in Oslo that a man dressed wearing a police uniform and identifying himself as a officer arrived by boat at Utoya Island, where word was spreading among the campers about the explosion in the capital, Pracon said.
The 700 teens and young adults attending the camp were gathered in a large meeting room where camp organizers were sharing information about the bombing in Olso when the police officer asked if he could address the group, Pracon said.
"We, of course, allowed him to come" in and address the group, Pracon said.
It was then, Pracon says, the man started shooting.
What followed, Pracon says, was panic and chaos as some campers ran from the shooter, while others went towards the man because they believed it was a drill or a test.
Many who fled ran toward the shore, jumping in the water to try to swim the three-fourths of a mile of water between the island and the mainland.
Pracon was among those who attempted to swim, but was forced to turn back.
"I felt I couldn't breathe. I already swallowed too much water. I also jumped because I was the last person running to the shore from this man. So I didn't have time to take my clothes off. As I was swimming, I felt the clothes pulling me down because they were heavy boots, clothes," he said.
" ... I wasn't sure if I was going to make it because I was already exhausted."
Labour Party member Bjorn Jarle Roberg-Larsen told CNN that the man told campers he was there to carry out a security check.
"After just a few minutes, he took a handgun and started to shoot people," Roberg-Larsen said. "A panic broke out; people tried to hide; some jumped into the water and tried to swim ashore."
Others took shelter in caves or bushes, or climbed trees. "And he went after them," the party member said. "Unfortunately, a lot of people are wounded and also a lot of people are dead."
Pracon said the shooter chased people to the shore, screaming at them as he fired at them.
Pracon was lying on the shore when the gunmen opened fire at those in the water and on the shore.
"I was maybe 5, maybe 7 meters away from him as he was yelling he was going to kill you all and we all shall die. He pointed his gun at me, but he didn't pull the trigger," Pracon said.
"He left and returned maybe an hour later ... he shot almost everyone. Me and two others were laying down and survived because of the bodies we could hang on to and pretend that we are dead."
Frykholm, the police spokesman, said that the man arrested on the island appeared to match the description of a person who was seen near the government buildings shortly before the bomb erupted.
The man, whose identity has not been released by authorities, does not work for police, Frykholm said.
