Dia coordinated the arrest in France of Domenico Stanganelli, a fugitive since 2014 and recipient of a European arrest warrant for mafia-type association, smuggling, money laundering, port and illegal possession of weapons in the context of a investigation that hit the Molè from Gioia Tauro and Mancuso from Nicotera. Stanganelli was arrested at the home of his in-laws in Vallauris, on the Côte d'Azur, thanks to the cooperation between Dia and the Judicial Police of Marseille and Nice.
