U.S. Customs and Border Protection officers at the local port of entry cargo inspection facility intercepted a shipment of marijuana last week worth up to $12 million.

The seizure occurred after CBP officers selected a 1994 International tractor-trailer, driven by a 26-year-old man from Nogales, Sonora, Mexico, for a thorough inspection. Inside the trailer, CBP officers found 600 bales of marijuana weighing a combined 14,151 pounds. The bales were packaged in boxes manifested as steel containers.

Officers seized the marijuana and conveyance. The driver was turned over to Immigration and Customs Enforcement’s Homeland Security Investigations.
