Italy's Anti-Mafia Directorate (DIA) has seized three billion euros in assets from the Neapolitan Camorra crime syndicate since the DIA was set up in 1991, the Ansa news agency reported on Monday.
Italian authorities said last year the DIA seized more than 380 million euros and confiscated another 137 million from the Naples mob.
It arrested 112 suspects and set up probes on 341 companies, they added.
