PERNIK police busted a criminal ring that carried out credit card frauds throughout the country.

The investigation showed that individuals and firms had made illegal bank transactions over the past year. The alleged frauds drained the accounts of foreign credit card owners. They used the personal data of the owners as well as the credit card numbers.

To order bank payments, they presented forged invoices "proving" apparently legal deals of real companies. During the operation, police took by surprise six of the alleged fraudsters while they were processing another account drain in a business office.

The officers seized foreign nationals' papers, MasterCards and Visa cards, numerous documents, post-terminal devices and a computer that was allegedly used in the transactions. Three of the those arrested remained in custody. The investigation was continuing as investigations try to unravel the mechanism of the frauds.
