Spanish authorities have dismantled a basic part of an international cocaine trafficking network, arresting two brothers in Arnedo, La Rioja. During a search of one suspect’s home, officers from the Guardia Civil’s Unidad Central Operativa (UCO) found almost €1 million in cash, packed into three shoeboxes and hidden under a bed. Both brothers are business owners. They are accused of using their companies to help large cocaine shipments into Europe for an Albanian-led organization operating from Dubai.
Investigators say the brothers managed a dozen companies involved in road transport, fruit and vegetable imports, and wholesale cosmetics. Those businesses allegedly provided commercial cover for shipments moving through the Spanish ports of Málaga, Valencia, and Algeciras. Cargoes included bananas, pineapples, onions, timber, and scrap metal. Cocaine, mainly shipped from Guayaquil, Ecuador, was concealed in legitimate cargo, while the companies are also suspected of helping launder proceeds from drug sales.
The trafficking route reflects a wider pattern: cocaine concealed in ordinary containerized exports. In a separate Ecuadorian case, the newspaper Extra reported that eight tonnes of cocaine were hidden in 12 of the 20 pallets in a banana shipment from Guayaquil to Rotterdam. The estimated value on Europe’s illicit market was €600 million. Investigators in that case concluded the drugs had been placed in the cargo on land, rather than introduced at sea. About 20 people were later placed under investigation by Ecuador’s Fiscalía General del Estado. That case shows how legitimate export documentation and cargo chains can be exploited, but it is distinct from Operación Mondragón.
Between August 2023 and November 2024, investigators linked the Mondragón inquiry to seven major cocaine seizures in Ecuador, Brazil, and Spain, totaling more than 21 tonnes. The operation resulted in 44 arrests: eight in Spain and 36 in Ecuador. The younger brother, identified by investigators as the group’s leader, was detained in January 2025 after a seizure in Valencia and has remained in custody since. His brother was arrested in July 2025, the day officers found the cash. Both reportedly maintained a high standard of living while avoiding conspicuous displays of wealth.
Six other suspects of Spanish and Moroccan nationality were also detained for their alleged involvement. Police searched properties in Alicante, Seville, and Cádiz, and froze property, vehicles, and financial assets linked to the network. In Ecuador, local police, supported by the Guardia Civil, carried out around 50 searches in March 2025 as part of an operation targeting the network’s logistics. Investigators believe Albanian investors based in Dubai financed cocaine purchases and injected large sums into Spanish companies, disguising the nature of shipments and payments.
The case shows how international trafficking networks combine maritime freight with domestic businesses and cross-border finance. Spain’s ports link European markets to major shipping routes from Latin America, while containerized trade gives legitimate exporters access to established logistics infrastructure. Investigators are examining company ownership and financial flows alongside cargo movements, a reflection of the challenge of distinguishing ordinary commerce from alleged criminal activity. A separate report on emergency care in Madrid also discussed the impact of organized crime on public services and security; it can be found here.
The investigation into the La Rioja network is ongoing. Its outcome may clarify how the alleged group used commercial companies to support cocaine shipments and move proceeds across borders, as Spanish and Ecuadorian authorities continue their joint work against the network.
