Carminati frequented a bar that was a haunt of Rome criminals and political extremists . He became a particular friend of Valerio Fioravanti , leader of the far right terrorist group '' Nuclei Armati Rivoluzionari '' ( " Armed Revolutionary Nuclei " , or NAR ) . Carminati introduced Fioravanti to some Banda della Magliana members , including their leader Franco Giuseppucci , who became a close friend of Carminati , and Massimo Sparti who later became the main witness against Fioravanti for the 1980 Bologna train station bombing . After '' Nuclei Armati Rivoluzionari '' and Banda della Magliana ceased to exist through arrests and violent death , Carminati managed to emerge as a figure in his own right
