The Guardia Civil discovered, Wednesday, a clandestine tunnel linking an industrial warehouse in Ceuta's Tarajal industrial estate—shut down for years—to Morocco. According to El Mundo, the underground passage was used to smuggle hashish. The traffickers repurposed old pipelines that once carried water from springs near the former Ceuta brewery to facilitate the drug transfer. Sources close to the investigation revealed that the tunnel was excavated discreetly using construction machinery inside the warehouse, ensuring it remained undetectable from the outside. Once completed, the tunnel allowed drugs to be transported directly from Morocco to Ceuta. From there, the shipments were loaded onto trucks and smuggled past port controls, allegedly with the help of corrupt agents on the organization's payroll. This discovery marks the third phase of an ongoing operation that has already led to multiple arrests, including two Civil Guards, a deputy from the MDyC party—a left-wing autonomist party in Ceuta—and a prison officer. Some detainees remain in custody, and further arrests are expected in the coming days. Since late January, the Civil Guard's Internal Affairs Department has been investigating a potential large-scale drug trafficking network that used heavy vehicles and semi-trailers to transport narcotics from Ceuta to mainland Spain.
