Italian police on Friday announced the arrest of the 79-year-old mafia boss of Corleone -- the Sicilian hilltop town made famous by \"The Godfather\" trilogy -- following a three-year investigation. Gaetano Riina is the brother of former Cosa Nostra kingpin Toto Riina, who is serving multiple life sentences for sanctioning scores of killings. Riina was picked up in the city of Mazara del Vallo where he was living while allegedly controlling the Corleone clan, the police said in a statement. The charges against Riina and three other men arrested on Friday including two of his relatives are for extortion and criminal association. The police said the clan has continued to play a \"central role\" in the mafia despite multiple arrests of the crime syndicate\'s historic leadership.
