CALEXICO, Calif. - Federal authorities say they seized more than 6,000 pounds of marijuana worth nearly $6 million hidden within a shipment of door knobs in a truck at the U.S.- Mexico Border.

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.
