There were scenes of celebrations at the Italian police headquarters in Palermo following the arrest of Gianni Nicchi, the alleged “number two” of the Costa Nostra mafia organisation.
Nicchi is only 28 years old but police say he has moved up rapidly through the mafia ranks as a result of the capture of several senior members.
Prime Minister Silvio Berlusconi sent his congratulations to the police and the government, saying the news pleased all fair-spirited Italians.
Police in Milan said they too have arrested a senior mafia boss, 78-year-old Gaetano Fidanzati.
