A man is in custody after U.S. Customs and Border Protection officers discovered over 146 pounds of alleged marijuana in his vehicle as he tried to cross into the United States on Sunday.

Officials said that the 21-year-old was driving a 1997 Ford F-150 from Mexico when he was stopped for a routine check at the Camino Real International Bridge.

After canine and non-intrusive imaging system checks, CBP discovered 58 packages containing alleged marijuana in the bed of the truck.

“Smugglers will go to any extent to cross a sizeable drug load,” Port Director John Brandt said.

The street value of the drugs totaled approximately $29,241.

The driver, a Mexican citizen, was taken into custody along with the narcotics and the vehicle.

“CBP officers used their training and experience to deter the shipment from making it to its intended destination,” Brandt said.

CBP writes that their mission continues to facilitate the flow of legitimate trade and travel by screening all people, vehicles, and goods entering the United States through our nation’s ports.
