Multiple Guardia Civil officers, including both active-duty and former personnel, have been arrested as part of a wide-ranging anti-drug operation centered on the discovery of sophisticated narcotics tunnels in Ceuta. The case has escalated rapidly, revealing not just a single instance of corruption but a broader pattern of alleged links between law enforcement and a highly organized trafficking network operating across the Strait of Gibraltar.

At the center of the investigation is the discovery of at least one, and potentially multiple, narcotunnels in the El Tarajal industrial zone, a highly sensitive area along the border with Morocco. The newly uncovered tunnel, estimated to extend roughly 20 meters, is believed to connect directly to Moroccan territory, possibly emerging near surveillance posts used by Moroccan auxiliary forces. This raises significant concerns about how such infrastructure could operate undetected in one of the most heavily monitored border zones in Europe.
The tunnels themselves represent a major leap in trafficking capability. Investigators describe complex underground systems featuring multiple levels, rail tracks, wagons, and mechanical hauling systems designed to transport large quantities of hashish efficiently and discreetly. In some cases, access points were concealed within industrial buildings, hidden behind soundproofed structures to avoid detection. These installations allowed for a continuous flow of narcotics from Morocco into Spanish territory, from where shipments were distributed to mainland Spain and onward to other European markets.
The investigation began over a year ago and initially focused on a Ceuta-based organization coordinating the steady movement of hashish into Europe. A key breakthrough came with the interception of approximately 15,000 kilograms of the drug in Almería, which enabled authorities to identify the network’s logistics chain, including negotiators at the source, transport coordinators, and distribution channels.
The involvement of Guardia Civil personnel has added a critical dimension to the case. Authorities are examining whether insider knowledge, such as patrol routines, surveillance blind spots, and border control procedures, may have been used to facilitate both the construction and operation of the tunnels. The fact that such infrastructure remained undetected for years is particularly striking given the scale of security resources deployed in the area, including more than 1,200 officers and surveillance systems backed by tens of millions of euros in investment.
Judicial authorities have ordered pre-trial detention for several of the suspects, including at least one Guardia Civil officer, citing the seriousness of the charges, which include membership in a criminal organization and drug trafficking. The investigation remains under judicial secrecy, and further arrests have not been ruled out.
Some reports have suggested that the engineering of the tunnels may have involved external expertise, including claims of involvement by individuals experienced in constructing underground systems in conflict zones in the Levant.
The case underscores the increasing sophistication of drug trafficking networks in southern Spain and highlights the strategic importance of Ceuta as a gateway into Europe. It also raises broader concerns about the dangerous connection between organized crime and Spanish law enforcement, particularly when infrastructure of this scale is able to operate undetected within one of the most heavily fortified borders on the continent.
