On the night of 15 to 16 October 2026, a large road-checkpoint operation took place on the A9 motorway in the France-to-Spain direction.[1] From 11 pm, the motorway was blocked and all vehicles were redirected to the Salses-le-Chateau rest area.[1] The departmental flow-control squadron led military personnel, a dog team and other state services including the biodiversity office, tax offices and Urssaf.[1]

Officers checked 250 vehicles carrying 320 people at the rest area.[1] Officers arrested one person found with 5.7 kg of cannabis resin.[1] The unit commander said the 5.7 kg of cannabis resin was travelling from Toulouse toward Perpignan.[2] Five other people tested positive for drugs and two for alcohol.[1] Three more people were caught holding about five to ten grams of drugs each.[1]

Officers also found two wanted people in their files, including one sought under a court judgment with six months in prison to serve.[2] Traffic in the France-to-Spain direction was diverted for three hours without interruption.[2]
