CBP officers at the Otay Mesa Cargo port of entry seized more than seven tons of marijuana on Wednesday 6 June 2018 after stopping a tractor-trailer whose manifest declared a shipment of metal racks.[1][2] A CBP officer working with Mexican Aduana-SAT referred the truck for X-ray examination, and a human-narcotic detector dog alerted to the trailer.[1][2]

Officers opened the trailer and found boxes holding plastic-wrapped packages: 722 packages containing about 14,965 pounds (about 6.79 tonnes) of marijuana, valued at about $8.6 million.[1][2] The 45-year-old Mexican driver had his B1/B2 visa cancelled and was turned over to Homeland Security Investigations agents for further processing; the truck, trailer, cargo and drugs were seized.[1][2]
