Major Police Operation Nets 42 Arrests in Crackdown on DZ Mafia in Southern France

A significant coordinated law enforcement operation took place on March 9, 2026, leading to the arrest of 42 individuals linked to the DZ Mafia criminal network across southern France. The arrests were part of an ongoing crackdown on the group, which has been involved in drug trafficking and violent crime in the region.

The operation, spearheaded by the interregional specialized jurisdiction (JIRS) in Marseille in collaboration with gendarmes from the Marseille research section, targeted multiple departments including Bouches-du-Rhône, Var, Vaucluse, and Gard. The suspects are currently in custody undergoing interrogation under the supervision of specialized magistrates.

Among those arrested are three presumed leaders of the DZ Mafia, who were already in prison. Law enforcement sources indicate that several lieutenants are believed to be orchestrating the organization's criminal activities directly from prison facilities in Condé-sur-Sarthe and Vendin-le-Vieil.

In addition to key gang members, the operation also uncovered the suspected corruption of a Lyon-based lawyer linked to the mafia, highlighting a potential legal facilitation of criminal activities. Authorities continue to investigate these connections as part of the wider probe.

This extensive operation follows an armed attack claimed by the DZ Mafia in Marseille's Belsunce district on January 4, 2026, which catalyzed intensified efforts against the criminal group. The campaign against the DZ Mafia has been ongoing for three years, aiming to dismantle their drug trafficking network.

Marseille’s public prosecutor, Nicolas Bessone, announced plans to provide further updates in a press conference scheduled for March 14, 2026.

This unprecedented round-up marks a major milestone in France's fight against organized crime, particularly targeting sophisticated networks exerting influence from prison. As investigations continue, authorities seek to disrupt the DZ Mafia's operations fully and bring additional suspects to justice.
