Officers at the Mariposa Commercial Facility arrested a tractor-trailer driver on Wednesday 7 December 2016 after finding more than 10,000 pounds (about 4.5 tonnes) of marijuana in his truck at the Port of Nogales.[1][2] The drugs were hidden inside a shipment of vacuum pump parts.[1][2]

Dog alert led to the find

Officers working with a narcotics-detection canine discovered the marijuana in the rig and valued it at an estimated $5.04 million.[1] The driver, a 23-year-old man from Nogales in the Mexican state of Sonora, was arrested.[1][2] The agency called it the eighth-largest marijuana seizure by officers of its Tucson Field Office.[1]

Truck seized, driver handed over

Officers seized the drugs and the vehicle and turned the driver over to Homeland Security Investigations.[1] The Associated Press account, carried by the Arizona Daily Star, confirms the same Wednesday arrest, the vacuum pump parts cover load and the estimated $5 million value.[2]
