The Guardia Civil dismantled a drug-trafficking organisation operating in Collado Mediano and Cercedilla and arrested six people.[1] The six were held on suspicion of drug trafficking against public health and membership in a criminal organisation.[2] Investigators described the network as a three-tier pyramid.[1] A 30-year-old woman led the group, managing supply between the homes and collecting payments.[2] The other five members were men aged 18 to 34, with two supplying the sale points and three making final sales to consumers.[2] Final sales took place directly from the homes and through home deliveries using four vehicles registered to third parties.[1]

The seized drugs included 214 grams of heroin and various batches of hashish and cocaine, plus precision scales, dosing tools, four private vehicles and 6.151 euros in cash.[1] The investigation, which started in late 2025, ended with the arrests on 27 October after neighbour complaints about homes in the La Cobañera urbanisation in Collado Mediano with constant short-stay movements of people and vehicles.[2]

The case began after repeated citizen complaints in a Collado Mediano housing estate about incessant buyers arriving by vehicle or on foot for very brief periods.[1] Early inquiries confirmed two flats in independent portals selling drugs around the clock every day.[1] Agents then found the Collado Mediano activity directly connected to two other homes in Cercedilla.[1]
