arrested in Milan. On 30 August 2007, hundreds of police raided the town of San Luca, the focal point of the bitter San Luca feud between rival clans among the 'Ndrangheta. Over 30 men and women, linked to the killing of six Italian men in Germany, were arrested. Since 30 March 2010, the 'Ndrangheta has been considered an organisation of mafia-type association according to 416 bis under the Italian penal code. In March 2011, the Ndrangheta expanded into northern Italy due to their "unlimited financial resources" according to the Italian Anti-Mafia Commission. On 4 June 2012, numerous arrests in Spain, Croatia, Slovenia, Italy, the Netherlands, Bulgaria, and Finland were made following the Milan District Anti-Mafia Prosecutor's Office investigation into several Switzerland bank accounts and a fleet of ships that supported cocaine shipped to Europe from Venezuela, Argentina, and the Dominican Republic.

On 10 October 2012, the commissioner of Milan's regional government in charge of public housing, Domenico Zambetti of People of Freedom (PDL), was arrested on accusations he paid the 'Ndrangheta in exchange for an election victory and to extort favours and contracts from the housing official, including construction tenders for the World Expo 2015 in Milan. The probe of alleged vote-buying underscores the infiltration of the 'Ndrangheta in the political machine of Italy's affluent northern Lombardy region. Zambetti's arrest marked the biggest case of 'Ndrangheta infiltration so far uncovered in northern Italy and prompted calls for Lombardy governor Roberto Formigoni to resign."Formigoni's Cabinet Member Arrested for Election Fraud" , Corriere della Sera, 10 October 2012.
