An investigation into far-right extremist groups in Italy led to the police finding an air-to-air missile, machine guns and rocket launchers. The huge weapons haul was almost without precedent, authorities said.
Among those arrested on Monday was a former candidate for the neo-fascist Forza Nuova party. His home was found to have the missile and weapons including a Scorpion machine gun, 306 firearm parts, 20 bayonets and more than 800 bullets of various calibers. The arms were primarily from Austria, Germany and the United States. Neo-Nazi propaganda was also found at the house, police said.
"During the operation, an air-to-air missile in perfect working order and used by the Qatari army was seized," police said of the 245-kilogram (540-pound) Mantra Super 530 F missile. They also found "latest generation" automatic assault rifles.
Police ruled out a terrorist action, with counter-terrorism official Eugenio Spina saying "For now, nothing leads us to suspect" an active plot to use the weapons.
It appears more likely the three were involved in marketing the weapons. The Digos law enforcement agency deals largely with terrorism and organized crime. It led the operation from Turin with assistance from police in Forli, Milan, Novara and Varese.
Carlo Ambra, the chief of the Turin unit of Digos, said investigators had intercepted phone conversations: "The most important thing for now is that we managed to block the sale of these arms."
