Spain’s National Police (Policía Nacional), working alongside Madrid’s Municipal Police, carried out a large-scale, dawn operation on 17 September 2026 against a drug-trafficking network operating across the southern Madrid region and into the neighbouring province of Toledo, arresting 19 people and dismantling 16 properties — so-called “narcopisos”, or drug-dealing flats — that the organisation used as storage points and sales outlets.
The raids were concentrated in the Villaverde district of Madrid, where the majority of the 16 targeted properties were located, but also extended into the districts of Vicálvaro and Latina within the capital, and into surrounding municipalities including Pinto, Fuenlabrada, Leganés and Móstoles. The operation also reached the town of Seseña, just across the regional border in Toledo province, reflecting the geographic spread the network had developed for its storage and distribution activities. Officers moved simultaneously across the properties at dawn, a tactic investigators say is used deliberately in operations of this scale both to exploit the element of surprise and to prevent suspects from destroying evidence or drugs once they become aware that other addresses linked to the network are being raided.
Investigators describe the organisation as “a perfectly hierarchical and organised criminal group,” with distinct roles assigned to different members covering the storage, processing and street-level distribution of narcotics. Officers seized approximately 3 kilograms of cocaine and nearly 2 kilograms of heroin, along with around 9 kilograms of cutting agents used to adulterate the drugs before sale, as well as quantities of ketamine and “tusi” — the pink, synthetic cocaine cocktail that has become increasingly common in seizures across Spain. Alongside the narcotics, police recovered approximately €70,000 in cash, a revolver, a machete, and a range of equipment and paraphernalia used in the packaging and distribution of drugs.
The investigation that led to the 17 September raids began with Madrid’s Municipal Police, who had been independently looking into some of the properties later included in the operation before the case was escalated into a joint investigation with the National Police, whose broader resources and jurisdiction allowed the two forces to coordinate the wider, cross-district and cross-province sweep. Officials highlighted this collaboration as central to the scale of the operation’s success. Francisco Martín, the Madrid Government Delegate — the senior state representative responsible for coordinating security policy in the region — described the action as “extraordinary work” by the National Police in what he called a “spectacular operation” against drug trafficking affecting the region.
The properties targeted in the operation functioned as what Spanish police commonly refer to as narcopisos: residential flats, frequently rented or occupied under false or borrowed identities, that are converted into round-the-clock points of sale for drugs, often in buildings where other residents have complained for months or years about the disruption, noise and open drug use associated with a constant flow of buyers. Spanish police forces, particularly in Madrid, have increasingly prioritised large, coordinated operations against clusters of such properties rather than pursuing them individually, on the basis that dismantling an entire network’s storage and distribution infrastructure in a single, simultaneous action does more lasting damage to the organisation than piecemeal raids that allow the group to relocate its operations to nearby addresses.
Of the 19 people arrested, police said the investigation remained active and that the number of arrests and identified properties could still grow as officers continue analysing material seized in the raids, including documentation and communications recovered from the dismantled flats, in an effort to trace the group’s supply sources and financial structure. Officers stated that part of the objective of the operation was precisely to establish “the logistical and financial scope” of the organisation, beyond simply removing the drugs and cash found on the day of the raids — an indication that further arrests, asset seizures or charges connected to money laundering could follow as the investigation develops.
The operation adds to a series of significant anti-narcotics actions carried out by Spanish police forces in and around Madrid during September 2026, and illustrates the scale that drug-distribution networks in the capital’s southern metropolitan belt — an area with a long-documented concentration of narcopisos — have been able to reach, spanning multiple municipalities and, in this case, crossing a regional boundary into Castilla-La Mancha. Investigators say the coordinated, multi-property model uncovered in Villaverde, Vicálvaro, Latina, Pinto, Fuenlabrada, Leganés, Móstoles and Seseña is broadly consistent with the way larger, more organised trafficking groups have adapted to sustained police pressure on individual drug flats by diversifying their points of sale across a wider geographic area.
