Hungarian authorities on Wednesday arrested a 45-year-old Norwegian man in his Budapest apartment who is believed to be planning a deadly attack to overshadow the 2011 killings of Norwegian far-right extremist Anders Breivik, police said.

The man, who has not been named, had made several posts on a video-sharing platform in which he described his plans to commit mass killings at an unspecified location.

According to Hungarian police, the suspect, who spoke mainly Norwegian and in some cases English, said he wanted to cover up Breivik’s crimes.

“I can hit anywhere…Airport, railway terminal, nothing would be a problem…I will destroy the innocent,” the suspect is quoted as saying in the videos he posted.

In July 2011, Breivik killed 77 people in Norway’s worst peacetime attack. He killed eight people with a car bomb in Oslo and then another 69 with a gun — most of them teenagers, vacationing at a Labor Party youth camp on the island of Utoja.

The 45-year-old has been detained in a mental institution and – according to Hungarian police – has been convicted of various cases of violence and sexual crimes in Norway.
