U.S. Customs and Border Protection said in a statement Sunday that officers seized the marijuana Friday night at a cargo inspection area at the border in Calexico, about 120 miles east of San Diego.
A team of dogs alerted officers to the truck, where they found 458 wrapped packages of marijuana in 67 cardboard boxes. Authorities say the pot had a street value of $5.9 million dollars.
The driver – a 30-year-old man from Mexicali, Mexico – was arrested. His name has not been released.
