Recent operations have highlighted an alarming phenomenon: the collaboration of security force members with drug trafficking networks. This issue, affecting various areas of the southern peninsula, from Cádiz to Seville, including the Bajo Guadalquivir and the Costa del Sol, reveals a disturbing evolution in the fight against organized crime.
A notable example is the case of Óscar Sánchez, former head of the Economic Crimes and Money Laundering Section of the Madrid Superior Police Headquarters, arrested in November 2024. His home in Alcalá de Henares contained 20 million euros, with nearly another million found in his office. The Audiencia Nacional links him to the introduction of 73 tons of cocaine into Spain, valued at over 2.5 billion euros. While this is one of the most impactful cases, it is not an isolated incident.
The presence of corrupt agents, though a minority among the 156,000 national police and civil guards, generates a disproportionate impact. Each infiltration case not only harms the institution but also undermines trust in the units where these individuals operated in secret. The situation worsens when drug trafficking manages to penetrate state structures, turning the criminal threat into a systemic challenge.
While Cádiz, especially the Campo de Gibraltar and the Costa Noroeste, remains a crucial entry point for drugs, police pressure has led to a diversification of routes inland, including towns like Chiclana and areas of the Bajo Guadalquivir. Seville, for its part, has consolidated as a key logistical hub, where criminal organizations use modified vehicles, seemingly legal warehouses, and shell companies to move large quantities of narcotics.
Arrests in the province of Seville have revealed that internal information is a valuable asset for drug traffickers, allowing them to anticipate police operations. Cases such as the arrest of half the staff at the Isla Mayor Civil Guard post in January 2017, or the convictions of agents for bribery and disclosure of secrets in February 2025 and 2024, underscore the seriousness of the problem.
The Costa del Sol, with its international dimension, is a complex ecosystem where drug trafficking intertwines with money laundering and the underground economy. Here, the possibility of leaks by "moles" – agents or officials who provide information – is a strategic tool for criminal organizations, eroding the state's ability to act effectively.
Experts warn that the situation in Spain, though not identical, offers parallels with Mexico's experience, where the infiltration of cartels into institutions led to a progressive loss of control. Isolated corruption and leaks are the first steps in a process that must be detected and stopped forcefully to preserve the system's credibility and public trust.
