Argentina's federal police arrested a top Italian mobster on the outskirts of Buenos Aires, the security agency said in a statement Monday, bringing a years-long manhunt to an end. Carmine Alfonso Maiorano, a 68-year-old leader of the Italian 'Ndrangheta mafia, was captured last Wednesday in the town of Guernica in the province of Buenos Aires, the statement said. The Italian-born Maiorano has been accused by international authorities of carrying out drug trafficking and arms trafficking operations between Latin America and Europe.
