Police stopped a fish-transport truck in San Mateo, Esmeraldas, on the morning of 26 March 2023 and detained its driver.[1] A judge in Esmeraldas ordered pretrial detention for the driver, identified as Clever Riol A. V., over alleged large-scale trafficking of controlled substances.[1] The judge opened a 30-day preliminary investigation after the flagrancy hearing.[1] The court ordered the seizure, retention and prohibition on sale of the truck used in the incident.[1]

Officers found the drugs in a hidden compartment discovered during a detailed search of the truck.[1] Inside were 524 rectangular packages wrapped in brown packing tape and black plastic with green plant material, plus three similar packages with white powder.[1] Weighing and preliminary field tests identified 511,680 grams of marijuana and 2,730 grams of cocaine.[1] Police initially described the load as 514 kilos of drugs concealed in the rear of the truck.[2] El Comercio reported the packages included both marijuana and cocaine and that the driver was detained.[2]

Prosecutors are pursuing the case as large-scale trafficking under article 220 of the COIP, which provides for ten to thirteen years of imprisonment.[1]
