Aude gendarmes, customs officers from Narbonne and Carcassonne and staff of the regional environment directorate (Dreal) Occitanie ran checks on the A9 motorway at the Fitou service area and on the D 6009 coastal road in the night of Tuesday 13 to Wednesday 14 May, between 11 pm and 2 am.[1] The operation involved gendarmes from the Narbonne, Carcassonne and Limoux companies and the departmental road safety squadron, and was part of the departmental plan for restoring everyday security (PADRSQ).[1]

During the three hours of checks 410 people were stopped.[1] Officers seized 21 kg of cannabis herb and 3.3 kg of cannabis resin.[1] More than 24 kg of cannabis was found in a single vehicle stopped on the A9, and the two people in it were arrested.[1] On the afternoon of 15 May the two occupants were still in police custody.[1]

The checks also produced one insurance fine, two roadworthiness failures, a transport-company offence and a drink-driving finding.[1] The PADRSQ had been presented in February 2025 by the prefect of the Aude, and includes action against drug trafficking.[1] The Gendarmerie de l’Aude published photographs of the 3.3 kg of resin and of the officers at the roadside checks.[2]
