LOUISVILLE, Ky. (WDRB) - Indiana State Police arrested and charged two Louisville men with fraud, after they were pulled over during a traffic stop, according to a news release.

Rene Perez, 29, and Brian Diaz, 24, both from Louisville, were arrested on Thursday afternoon after police discovered more than 170 credit cards during a search of the men's vehicle. The two men were arrested on I-65 south, near the 49 mile marker in Seymour.

Police were first alerted to the vehicle after an officer witnessed a blue 2005 Mercedes make "an unsafe lane change." A state trooper pulled the vehicle over; the officer became suspicious when talking with the driver.

The driver of the car gave the officer permission to conduct a search, at which time the credit cards were located.

Officials with the United States Secret Service determined that the recovered cards "had stolen credit card numbers on them."

Perez and Diaz are each charged with one count of fraud. The pair is being held at the Jackson County Jail in Indiana.

Investigators say more charges could be pending in the case.
