ROME — Italian police on Sunday arrested a man suspected of being an IS sympathiser who was found to have a collection of home-made explosive devices and detonators.

Italy’s interior ministry said the man, whose nationality was not given, was arrested in Castello di Cisterna in Naples after investigators monitoring the internet found a video of an Islamic State (IS) group decapitation on his Facebook page.

Police discovered weapons including three home-made mortar shells, two electronic devices for setting off explosives at a distance, 146 fuses, various detonators and a remote control, the ministry said in a statement.

Along with the IS video, the man had posted phrases on the social networking site in support of the Camorra, the notorious Naples-based mafia syndicate. — AFP
