A large-scale arms trafficking ring operating from a Catalan prison has been broken up. The group, led by an inmate and involving his family, sold weapons and explosives across Spain and France. Nine arrests and 45 weapons seized.
A coordinated police operation in Catalonia has exposed a sophisticated arms trafficking network run from inside the Quatre Camins prison. The group, led by a 37-year-old inmate serving a homicide sentence since 2009, relied on close family members to manage logistics, marketing, and distribution of illegal weapons and explosives. Authorities arrested nine people and seized a cache including 45 firearms, a grenade, thousands of rounds of ammunition—some classified as military-grade—and significant quantities of explosives. Prices for the illicit arsenal ranged from €4,000 to over €100,000, depending on the weapon and ammunition involved.
Investigators from Mossos d’Esquadra and the Policía Nacional revealed that the operation was orchestrated through illegally smuggled mobile phones, allowing the imprisoned leader to maintain constant contact with his network. The family’s involvement was central: the inmate’s daughter produced promotional videos demonstrating the weapons’ features and functionality, which were then circulated to potential buyers via WhatsApp, Telegram, and Signal. Meanwhile, the mother handled the physical distribution, often delivering arms in public parking lots and commercial areas with a level of discretion that surprised police.
The investigation began as an offshoot of a broader criminal probe launched in December 2025, eventually identifying the prison-based ringleader in January. The family home served as the main storage site, with most weapons kept in a car parked outside the building. The group’s operations were described as highly organized, with a clear division of roles: the core family managed sales and logistics, while a secondary network of collaborators sourced specific weapons on demand for clients.
Police sources emphasized that the network’s clientele consisted exclusively of organized crime groups, not private collectors. The group’s ability to supply a wide range of firearms—including AR-15 and AK-47 rifles, high-capacity shotguns, handguns, grenades, and war ammunition—meant that the only real limitation was the buyer’s budget. The operation supplied arms not only within Catalonia but also to the Comunidad Valenciana, Madrid, and even France, disrupting what authorities described as a major supply chain for criminal organizations.
During the raids, officers discovered that 38 of the 45 seized firearms were expertly counterfeited handguns, convincing enough that buyers reportedly had no concerns about their authenticity. The investigation remains open, with particular focus on the financial aspects and the broader distribution network across Spain.
This case highlights the evolving tactics of organized crime in Spain, where family structures and digital communication tools are increasingly used to evade detection. The use of encrypted messaging apps and the involvement of relatives in both marketing and logistics reflect a trend seen in other recent criminal investigations. For context, Catalonia has faced several high-profile violent incidents in recent years, such as the case in Lleida where police responded to a violent death, as reported in coverage of serious incidents in Lleida and Girona.
Spain’s legal framework imposes strict penalties for arms trafficking, and authorities continue to prioritize dismantling supply chains that feed organized crime. The current operation underscores the challenges law enforcement faces in tracking illicit arms flows, especially when criminal groups adapt quickly to new technologies and exploit family ties to maintain secrecy. The ongoing investigation is expected to yield further arrests and shed light on the financial mechanisms underpinning the trade.
