London woman held as Italians fear plot to target synagogue Police said Jarmoune had lived in Italy since he was six years old but he had "come across their radar" as part of another investigation and when they began investigating his background discovered he had been looking at several Islamic extremist websites. He had downloaded images of the synagogue and other information such as security measures and officers also discovered a pencil diagram appearing to show a series of four gas canisters connected to a battery which was also linked to a mobile telephone, while other images showed the preparation of explosives Police said he had created seven 'super secret' Facebook profiles to discuss terror tactics on line - one of which was with the woman held in London - and ten email addresses and he had insisted to subscribers that they "discuss only weapons and explosives and not post videos of religious songs." Brescia police chief Lucio Carluccio said:"We are not talking about a traditional criminal terror organisation, those groups are now fewer and fewer but what we are talking about is isolated groups springing up of young men who contact each other via the internet." The woman was held under Section 58 of the Terrorism Act on suspicion of "possessing a document or record containing information of a kind likely to be useful to a person committing or preparing an act of terrorism." Searches were last night ongoing at her home.
