There seems to be a lot of Sicilian Mafia, Ndrangheta and Camorra involvement in Rome. The Sinti clans seem to be the most prominent "local" type of organized crime (even though their origins are in Abruzzo), but law enforcement has been coming down on them hard.
i think there are other gangs based in some neighborhoods on the same level of Casamonica and Spada sinti clans as the Cordaro's in Tor Bella Monaca or the Gambacurta's and Cascalisci's; there are also members of the Banda della Magliana still active although the gang was dismantled in the 1990s
