DR ‹ › Investigations by the Spanish police have unveiled a startling revelation: the secret tunnel recently discovered linking the industrial zone of Tarajal in Ceuta to Morocco was not just a conduit for drug trafficking. It was also, at times, a passageway for the clandestine entry of migrants into the city. According to legal experts and sources well-versed in drug trafficking operations, these tunnels are not isolated phenomena but part of a sophisticated network employed by criminal organizations. They are sometimes repurposed for smuggling weapons or transporting people for hefty fees paid to the network's leaders. This aligns with information from security sources, who have noted instances of migrants appearing in recent years without clear evidence of their entry points, suggesting these tunnels have been used for various illicit activities. Investigations continue under a shroud of secrecy, with authorities suspecting that the criminal network began exploiting the tunnel after the marble company operating in the industrial warehouse ceased its activities. Efforts are underway to establish potential links between the current owner of the company and members of the network. Around thirty individuals are under suspicion, each allegedly fulfilling specific roles within the organization, ranging from planning to transportation and storage, according to a report by the anti-drug and organized crime unit. The network's alleged leader, dubbed «The King of Tunnels», is thought to be Mustapha Chairi Brouzi, identified through wiretapped communications. Security reports reveal that the tunnel comprises three levels and is outfitted with a system of pulleys and lifts, facilitating the smuggling of up to 8,000 kilograms of drugs monthly. This makes it more sophisticated than another tunnel uncovered last year, merely 100 meters away. There are also suspicions of involvement by a former member of the civil guard in aiding the network. On the judicial front, the Spanish National Court is pressing forward with the investigation after Central Investigating Judge No. 6 assumed responsibility, following the Ceuta court's decision to relinquish the case due to jurisdictional boundaries. A separate procedure has been initiated to delve deeper into the investigations at the behest of the public prosecutor's office.
