'No 1 Mafia Boss' Arrested Likeness: A computer generated image of how Bernado Provenzano was thought to look Italy's reputed No 1 Mafia boss, Bernardo Provenzano, has been arrested in Sicily, the ANSA news agency has reported. The information was claimed to have come from Italian prosecutors. Provenzano, Italy's most wanted man, went on the run more than four decades ago. He is believed to have taken over the Sicilian Mafia after the 1993 arrest of former boss Salvatore "Toto" Riina in Palermo. As recently as last month, Provenzano's former lawyer was quoted as telling an Italian newspaper that the elusive man was dead. "I think Provenzano's dead, and has been dead for several years," Salvatore Traina was quoted as telling Rome-based daily La Repubblica. "They have looked for him everywhere, they have looked intensely for years, but they can't find him. This must mean something."
