EL PASO, Texas -- Bundles of marijuana were found inside dog food bags Wednesday by officials at the Bridge of the Americas.

A drug-sniffing dog alerted U.S. Customs and Border Protection officers to the trunk of 2009 Peugeot. CBP officers opened the trunk and found large bags of dog food, but when they opened them up, marijuana was found inside.

CBP officers removed 30 marijuana-filled bundles from the dog food. The drugs weighed 31 pounds.

The driver, a 25-year-old Mexican male from Ciudad Juarez, was turned over to the El Paso County Sheriff’s Department for prosecution.
