Police impounded two companies worth more than 800,000 euros on Thursday from a jailed Calabrian businessman with ties to the local mafia or 'Ndrangheta.
The companies seized from businessman Gianluca Favara included a laundry in the Calabrian town Rosarno and a catering business in Campo Calabro, near Reggio Calabria.
Anti-mafia investigators ordered the property seizures from Favara, a native of the northern city of Milan.
Favara was in 2014 convicted of association with 'Ndrangheta clans in Rosarno and Reggio Calabria and sentenced to 10 years in prison.
He ran the business affairs of the 'Ndrangheta's condello di Archi clan in Reggio Calabria, including a prominent nightclub in the city, Il Limoneto (The Lemon Grove).
Prosecutors have impounded billions of euros of property from members of the Calabrian mafia or 'Ndrangheta and their associates in recent years.
Now Italy's wealthiest and most powerful crime syndicate, the 'Ndrangheta possesses virtually unlimited resources and has 'colonised' the wealthy industrialised north, according to Italy's national anti-mafia directorate.
The 'Ndrangheta operates throughout Italy as well as in Europe but its influence and networks extend from Australia to North and South America, where it has links to the main drugs cartels.
