The Mexican Army seized 950 pounds of methamphetamine, fentanyl, and heroin on Sunday in Baja California–adding to the number of significant drug busts within the past two months.

The 67th Infantry Battalion at a security checkpoint in El Rosario contacted the driver of a Chevrolet 3500 truck transporting two horses, according to local media. Troops detected a false compartment in the bed, storing plastic containers filled with illicit drugs. An inventory process yielded 705 containers with approximately 600 grams each of methamphetamine; four containers with a kilogram each of fentanyl; and two containers at a kilo each of heroin.

The seizure was part of “Opración Rocinante.” The total weight of the drugs seized was approximately 950 pounds, according to the Secretary of National Defense. The drugs were believed destined for the U.S. market.

The driver was arrested and his cargo transferred to the federal prosecutor’s office in Ensenada.

The El Rosario Baja California checkpoint is located south of Ensenada at the Baja California Norte–Baja California Sur line on Highway 1.
