The case builds on prior Italian investigations into online radicalisation of teenagers into violent supremacist and accelerationist milieus, including a June arrest of a 16-year-old discussing rebuilding a clandestine terrorist network targeting magistrates and journalists.

Polish authorities traced Paweł G. to groups such as Atomwaffen Polska, and possibly Bierut Soldier ZNB, placing him within a broader international extremist ecosystem.

Interceptions reportedly included plans for attacks on a mosque, a synagogue, and a school.

The operation was conducted by the Carabinieri ROS unit and Digos police across multiple cities, including Rome, Milan, Como, Bologna, Palermo and Verona.

The investigation expanded beyond initial suspects after a police raid in Łódź led to new inquiries and the identification of another potential participant in the wider network.

The groups allegedly used a pseudo-military hierarchy and recruited via Telegram.

Authorities found manifestos and propaganda from terrorists like Breivik, Tarrant, and Balliet, along with manuals on explosives and weapons and materials detailing violent direct actions.

Judicial authorities imposed a three-month pre-trial detention to prevent influence on witnesses or flight, underlining a hard stance against extremism.

The networks under scrutiny were Nuovo Ordine Europeo (New European Order) and Fronte Fascista Italiano, tied to accelerationist ideology, white supremacy, and neo-Nazism.

Cross-border connections are suspected, including a German minor linked to the networks, prompting international cooperation.

A Polish investigation led to the arrest of a 17-year-old Paweł G. in Katowice for planning a mass terror attack targeting a school and a mosque, with possible involvement of a young German national.

Online chats on Telegram and Discord fostered radicalization, with discussions about past attacks, potential future targets, and methods indicating activities beyond opinion-sharing.
