EL PASO, Texas (Border Report) — A pair of drug busts netted more than $8.7 million worth of narcotics last week at a South Texas border crossing, U.S. Customs and Border Protection said.

Both drug seizures occurred at the World Trade Bridge in Laredo, Texas.

On Friday, border officers conducted a non-intrusive imaging inspection on a tractor-trailer hauling a shipment of plastic containers. With the help of a drug-sniffing dog, officers found 137 packages containing 3,272 pounds of marijuana.

The previous day, border officers discovered 159 packages containing 581 pounds of methamphetamine in a tractor-trailer following a secondary inspection that also involved an NII and the assistance of a canine unit.
