ROME: A fugitive Italian mafia boss who has been linked to killings in the German city of Duisburg has been arrested in Lisbon, police said here on Tuesday. The man, a member of the 'Ndrangheta crime organisation, had disappeared in June 2019, shortly before he faced final sentencing by Italy's Court of Cassation to life imprisonment, reports dpa news agency. He was put on a list of most-wanted fugitives by the Italian Interior Ministry. The 'Ndrangheta hails from Calabria. It is the country's most powerful mafia and is considered the leading trafficker of cocaine in Europe. The arrest was made on Monday in the Portuguese capital, the police said. (IANS)
