Vikernes was arrested on 19 August 1993 in Bergen. The police found 150 kg of explosives and 3,000 rounds of ammunition in his home. According to the "Encyclopedia of White Power", Vikernes "intended to blow up Blitz House, the radical leftist and anarchist enclave in Oslo", a plan that "was reportedly on the verge of execution." In an article originally published in 1999, Kevin Coogan also mentioned Vikernes' alleged intent to "destroy an Oslo-based punk anti-fascist squat called Blitz House," and stated "Vikernes may have felt that he had no choice but to kill Euronymous before bombing Blitz House because 'the Communist' would almost certainly have opposed such an act." Vikernes denied these claims in a 2009 interview, saying he was collecting explosives and ammunition "in order to defend Norway if we were attacked any time."
