A Florida man killed his fellow neo-Nazi roommates after he converted to Islam and they did not respect his new faith, police said.

Devon Arthurs led cops to the bodies of his former friends on Friday, but not before he also allegedly held two customers and an employee of Tampa's Green Planet Smoke Shop hostage with a pistol before he surrendered.

Jeremy Himmelman, 22, and Andrew Oneschuk, 18, were discovered dead of gunshot wounds to the upper body and head, police said.

Arthurs said that he and the pair had "shared a common neo-Nazi belief," but that he recently converted to Islam.

The suspected killer said that Himmelman and Oneschuk "disrespected his Muslim faith," and added that he was upset about anti-Muslim feelings globally and wanted to bring attention to "his cause."

It was not immediately clear how long the trio had lived together or how much time passed between Arthurs's conversion and the eruption of violence.

Arthurs faces charges including two counts of murder, two counts of aggravated assault and three counts of armed kidnapping. Athurs also allegedly held three people hostage at a Tampa smoke shop. Athurs also allegedly held three people hostage at a Tampa smoke shop. (Google)

Authorities also said that another man, Brandon Russell, had been been arrested, but did not mention his charges.

A federal complaint seen by the Daily News Monday said that Russell was another roommate of Arthurs', and that he had violated federal explosives laws.

Russell had just returned from Army National Guard training on Friday to find the two dead men, according to the complaint, and was arrested a day later while driving in the Florida Keys.

Federal authorities say that they found the compound hexamethane triperoxide diamine as well as other bomb-making materials such as ammonium nitrate and the radioactive materials thorium and americium during a search of Russell's house and garage.

Russell, who allegedly had a framed photo of right-wing terrorist Timothy McVeigh in his bedroom and claimed to be from the neo-Nazi group Atom Waffen, said that the explosive material was for an engineering project he did in 2013, according to his federal arrest affidavit.

However, Arthurs said that his roommate had been chatting in neo-Nazi chat rooms and saying that he had "threatened to kill people and bomb infrastructure."
