Border police detained four men at Paris-Charles-de-Gaulle airport on 2 May 2026 as they were about to board a flight to Fort-de-France in Martinique.[1][2] Investigators then arrested a 29-year-old Guadeloupean man in Rennes on suspicion of heading the network.[1][3][2][4] The five suspects were placed in pretrial detention.[1][3][2][4] The Rennes prosecution service took over the case from Bobigny and assigned the investigation to OFAST, France’s anti-drug office.[5] The four airport suspects were brought back to Rennes and held in police custody there.[5]

A routine customs check of the couriers’ suitcases uncovered the cannabis.[1][6][2][4] Officers seized 185 kilograms of cannabis from those suitcases.[7][6][3][2][4] The load included pressed resin loaves and bags of cannabis herb.[5][6] The four are described as suspected drug transporters.[7][3] Investigators say they moved cannabis between Brittany and Martinique, where cannabis resin sells for more.[7]

OFAST investigators are working to reconstruct how the network operated and to identify other possible accomplices.[1][2][4] Investigators suspect a cross-trafficking scheme sending cannabis toward the islands and bringing cocaine back toward Europe.[1][3][2][4] The suspected Rennes organizer allegedly ran an import-export operation between mainland France and the overseas territories.[5] Reports present the Antilles route as lucrative because cannabis resells there for three times the mainland price.[5] The suspected method was to exchange cannabis for cocaine with no money changing hands.[5] Rennes prosecutor Frédéric Teillet said that account remains to be established by the judicial investigation.[5]

The five men were placed under formal investigation (mis en examen) in addition to being placed in pretrial detention.[3]
