The French prison system is moving its most dangerous inmates to highly secure facilities as part of an effort to combat organized crime. These facilities, known as "QLCO" (Quarters for the Fight Against Organized Crime), were created in response to the high-profile escape of Mohamed Amra in 2024 at the Incarville toll. A third QLCO has recently opened in Réau, Seine-et-Marne, joining existing ones in Vendin-Le-Vieil, Pas-de-Calais, and Condé-sur-Sarthe, Orne. Around a dozen inmates are now housed in the Réau facility, having been transferred from other prisons across France. Franceinfo observed one such transfer, which involved moving an inmate from the Moulins-Yzeure prison in Allier. The operation was carried out by elite prison security units, with agents dressed in black and equipped with advanced gear. Around forty operators from the regional intervention and security teams (ERIS) and elite prison units took part, with over a hundred agents involved in transporting three prisoners to the Réau QLCO. The prisoners moved to these facilities are considered to be among the most dangerous, holding high positions in international trafficking networks. They are believed to have the resources and influence to plan and execute violent escapes or attacks. The QLCOs are designed to isolate these individuals completely from the outside world to prevent them from continuing their criminal activities while in custody. Conditions in these ultra-secure facilities are much stricter than in regular prisons. Each prisoner is held in a separate cell designed to be nearly airtight, minimizing the possibility of communication with others. Each cell includes a bathroom and a fixed telephone, with all conversations monitored. Prisoners are allowed two sessions of two hours each week to communicate with others. Anti-communication devices are used to block mobile phones and drones. Cell doors are equipped with "handcuff traps" that allow guards to restrain prisoners without entering the cell. Prisoners can only go outside for walks in small groups, and family visits are limited to glass partitions. After any contact with the outside, full searches are conducted. Video conference rooms have also been installed to enable the judiciary to conduct hearings with prisoners without needing to extract them. The creation of these facilities has sparked debate. The International Prison Observatory, an NGO, has criticized the move as an example of "security paranoia" and a "negation of prisoners' rights." Some inmates have initiated legal procedures to challenge their detention conditions, and the lawyers of dozens of prisoners have contested their transfer to these high-security quarters. However, in 2025, the Council of State, France's highest administrative court, validated the system.
