Italian authorities say a network of European art forgers who painted fake Warhols, Banksys and Picassos and then tried to sell them to unsuspecting buyers with the help of complicit auction houses has been dismantled.

Investigators discovered six forgery workshops and seized more than 2,100 fake artworks with a potential market value of about $215 million.

The investigation so far spans Italy, Spain, France and Belgium, with suspects under investigation for conspiracy to handle stolen goods, forgery and illegal sale of artworks. News of the investigation was jointly announced by the paramilitary Carabinieri art squad and the Pisa prosecutors’ office and first reported by Reuters.
