'There is reason to think that this may be a hate crime,' police said. Two weapons, including a fully automatic gun, were retrieved from the crime scene, they added. Journalist Olav Roenneberg of public broadcaster NRK said he was in the area at the time and saw a man arrive with a bag, take out a gun and start to shoot: 'Then I saw windows breaking and understood that I had to take cover.'Ī suspect, a 42-year-old Norwegian citizen of Iranian origin, was detained minutes after embarking on the shooting spree, according to police who said they believed he acted alone.
