French gendarmes in the Ariège department have dismantled an organized network suspected of carrying out more than 20 thefts of copper and tools from hydroelectric power plants and French national railway company (SNCF) sites, causing damages exceeding €400,000. The operation, which concluded after several months of investigation, led to the arrest of six individuals and the seizure of luxury items, vehicles, and specialized equipment used in the crimes.
The investigation began in late 2025, following a series of targeted thefts that primarily struck hydroelectric infrastructure in the mountainous region of Ariège, in southwestern France. According to the gendarmerie, the suspects focused on copper wiring and industrial tools, which were then stripped and sold on the black market. The network is believed to have operated with a high degree of organization, using vehicles such as motocross bikes to access remote sites and stripping machines to process the stolen copper quickly.
During the arrests, authorities confiscated a range of assets, including several iPhones, motocross motorcycles, and copper stripping machines. The seized goods also included luxury items, reflecting the proceeds of the illicit activity. The total financial prejudice is estimated at over €400,000, though investigators believe the actual figure may be higher as additional thefts are being linked to the group.
The network specifically targeted hydroelectric plants, which are critical for energy production in the region, as well as SNCF infrastructure, including railway signaling equipment and power lines. The thefts caused significant operational disruptions, forcing temporary shutdowns of some facilities and delaying maintenance work. The copper, a valuable metal due to its high conductivity and recycling value, was likely sold to scrap dealers, though the investigation is ongoing to trace the full supply chain.
The six suspects, all believed to be part of a coordinated group, face charges of organized theft, criminal association, and damage to public infrastructure. They were taken into custody and are awaiting trial. The gendarmerie emphasized that the dismantling of this network was the result of close collaboration between local units and specialized investigative teams, highlighting the importance of inter-agency cooperation in tackling organized crime.
Copper theft has become a growing concern across Europe, driven by rising metal prices and the vulnerability of remote infrastructure. In France, such thefts have targeted not only energy and transport networks but also telecommunications and construction sites. The Ariège case underscores the challenges faced by authorities in protecting critical infrastructure from increasingly sophisticated criminal groups.
The investigation continues, with authorities examining whether the network is linked to similar thefts in neighboring departments. Meanwhile, the seized assets will be held as evidence, and efforts are underway to identify and compensate affected companies, including EDF (Électricité de France), which operates several hydroelectric plants in the region, and SNCF. The case has prompted calls for enhanced security measures at remote industrial sites, including better surveillance and the use of tamper-proof materials.
Local officials have praised the gendarmerie's work, noting that the dismantling of the network sends a strong message to organized crime groups operating in rural areas. The operation also highlights the economic and operational impact of metal theft, which can cost millions of euros annually in repairs and lost productivity. As the legal process moves forward, the case is expected to serve as a benchmark for future efforts to combat similar criminal enterprises.
