Czech authorities have arrested a 29-year-old man -- an admirer of Behring Breivik, the man accused of killing 77 people in Norway last year -- suspected of plotting a terrorist bombing, NBC News Reported. The man was apprehended on August 10 but the case was made public on Saturday. According to investigators, the suspect has multiple previous convictions for making illegal explosives, and was planning to detonate a high-power bomb. He was carrying a remote-control detonator when he was arrested and tests on the presumed bomb showed that it was "functional," police said. The man drew the attention of police by using the nickname "Breivik" in posts on Internet sites, authorities said Saturday, the Prague newspaper Czechia Today reported. When they searched his home in Ostrava, they defused a booby trap before discovering firearms, ammunition, gas masks and improvised explosive devices, as well as police uniforms, police said.
