Caserta, July 19 - Italian police on Friday arrested four suspected members and one suspected affiliate of a top Camorra clan operating out of the town of Marcianisce near Caserta. The five alleged members of the Belforte clan are suspected of mafia conspiracy, attempted murder, receiving stolen goods and weapons possession. The probe was linked to two murders committed by the clan, police said. The Camorra is a crime syndicate based in Naples. It is Italy's third-biggest mafia after Calabria's 'Ndrangheta and Cosa Nostra in Sicily.
