SAN ANTONIO -

Two Mexican citizens who were arrested at the border in connection with a credit card fraud case currently have no ties to the massive Target security breach, according to a report by the Associated Press.

McAllen police initially said the suspects, 28-year-old Daniel Guardiola Dominguez and 27-year-old Mary Carmen Garcia, used account information stolen during the Target security breach to buy tens of thousands of dollars' worth of merchandise this month.

However, a federal official with knowledge of the case said late Monday there currently was no connection between the McAllen case and any ongoing investigation into the breach, but would not elaborate.

The official spoke on condition of anonymity because the official was prohibited from providing details about the investigation, the AP reported. Messages left for McAllen Police Chief Victor Rodriguez and his lieutenant Monday evening weren't immediately returned, the AP reported.

Dominguez and Garcia were arrested Sunday at the Anzalduas International Bridge as they entered the U.S. Rodriguez said the suspects were found with an array of fraudulent credit cards, and personal information stolen from South Texas residents.

The Associated Press reported the discrepancy could not immediately be rectified and a Target spokeswoman referred questions to local law enforcement.
