Authorities are investigating how two people from Monterrey ended up with fake credit cards made using information taken in the Target data breach.
Hackers stole the personal information of millions of credit card users at Target stores across the United States late last year.
McAllen police have made two arrests that show what may have happened to the stolen data.
Investigators revealed that two people arrested at the Anzalduas International Bridge over the weekend were found with 96 cloned or counterfeit credit cards.
Both 28-year-old Daniel Guardiola-Dominguez and 27-year-old Mary Carmen Garcia were arrested after authorities found the credit cards under their clothes.
McAllen Police Chief Victor Rodriguez said their credit cards were made using data stolen from Rio Grande Valley residents during the Target data breach.
Chief Rodriguez said both Guardiola-Dominguez and Garcia came from Monterrey where there are already sophisticated credit card cloning and fraud rings.
McAllen police are working with federal officials to investigate how the two ended up with the cards, who made them and who provided them with the data.
