(ANSA) - ROME, NOV 7 - A Carabiniere and a retired Carabiniere, a Camorra boss turned informant's son and a businessmen were arrested Thursday in the 2010 Camora mafia murder of Angelo Vassallo, the so-called 'fisherman-mayor' of the seaside village of Pollica in southern Campania, who had denounced a local drug trafficking ring allegedly involving cops.
    Vassallo, 57, was gunned down outside his home on September 5, 2010, having openly fought organized crime and building speculators who have marred coasts and countryside all over the Mezzogiorno.
    Among his many battles to protect environmental and cultural heritage along Italy's lovely Cilento coast, Vassallo had denounced to police a drug trafficking ring operating around Pollica that was found to have been run by a Calabrian 'Ndrangheta mafia clan from the Cosenza area.
    Those arrested Thursday were: Carabinieri officer Fabio Cagnazzo; the son of the boss and police informant Romolo Ridosso of the Camorra Scafati Loreto-Ridosso clan; businessman Giuseppe Ciprian; and former Carabinieri brigadier Lazzaro Cioffi. (ANSA).
