Italian tax police blocked a total of 410 commercial websites Friday that were allegedly selling fake designer labels including Dolce & Gabbana, Fendi, Prada, Bulgari, Gucci and Giorgio Armani.
Other pirated labels available on the websites included Chanel, Cartier, Burberry, Rolex and Mont Blanc, Louis Vuitton, Christian Dior, Patek Philippe, Hermes and Moncler, police said.
Police closed down the websites and carried out raids in cities across Italy on the orders of prosecutors in Rome.
The operation "aimed to tackle illegal practices that have clearly harmful economic effects - job losses, tax evasion, links to organised crime and exploitation of child labour," police said in a statement.
"The pirated goods also posed health and safety risks to consumers," the statement added.
Italian tax police said they impounded pirated good worth around three billion euros last year. More than 8,400 people were reported to police in the course of over 9,500 seizure operations, police said.
