According to police officers, ten Romanian nationals and three Spanish nationals were part of an international network involved in credit card forgery operations in Italy, Spain and Romania.
Investigations started in April after somebody was reported to be spending large sums of money on various products in a shopping mall in Tarragona.
Following checkups, the police traced down the respective person alongside other people involved in such operations and discovered these illegal transactions were conducted in most shopping malls with the support of tradespeople.
The alleged head of the network, for whom the Italian authorities had previously issued a European arrest and extradition warrant, was arrested by the local police in Cambrils.
