Police arrested a Norwegian citizen in Hungary on suspicion that he was planning an extremist attack modeled after a 2011 massacre in Norway that killed 77 people, and would have taken place across airports, railway stations and on airplanes.

The National Investigation Office of the Hungarian police said the 45-year-old man had posted numerous videos to the internet in both English and Norwegian, in which he described his plans to commit the attacks, declaring in one video, “I will destroy the innocent!”

After analyzing the videos and identifying the suspect, Hungary’s Counter Terrorism Center arrested the man in a Budapest apartment and confiscated his electronic devices.

The suspect also described his desire to surpass the crimes committed by Norwegian far-right extremist Anders Behring Breivik, who killed 77 people in bomb-and-gun massacres in Norway in 2011.

During the latest investigation, Norwegian authorities informed Hungarian police that the man had earlier been convicted of numerous violent and sexual crimes in Norway. He has been remanded to Hungary’s Forensic Psychiatric and Mental Institution, according to police.
