170 arrested as Italian police crack down on organised crime

Italian authorities have carried out about 170 arrest warrants in a major crackdown on the 'ndrangheta, an organised crime syndicate in southern Italy which officials say has become deeply rooted in the business world in the north.

Italy's chief anti-mafia prosecutor Franco Roberti described the move as a "historic" step in the fight against the mob, during a news conference in Bologna.
