Between 30 May and 2 June 2025, the ten suspects were arrested in Guadeloupe during a large judicial operation by several gendarmerie units under the direction of the JIRS.[1] After their arrest, the ten suspects were placed under formal investigation and held in provisional detention.[1] France-Antilles reported that ten alleged traffickers were formally investigated and jailed in Guadeloupe on suspicion of taking part in a supply network that imported 15 tonnes of various drugs over two years.[2]

On 15 July 2024, the same research section learned that a drug delivery was imminent on a beach at Basse-Terre in Guadeloupe.[1] Supported by the Guadeloupe GIGN branch, investigators arrested three people landing on the beach and seized nearly 800 kg of cocaine and 27 kg of cannabis herb that had come from Dominica.[1] France-Antilles dates the joint Research Section and GIGN operation to the night of 14 to 15 July 2024, when three people were arrested on a beach at Capesterre-Belle-Eau.[2] It identified the three as two Guadeloupeans and one Dominican national caught recovering a cargo of 780 kg of cocaine and 26 kg of cannabis herb from Dominica.[2] The May-June 2025 operation also seized 20 kg of cannabis herb, a 900-gram cocaine brick, a category-B handgun, a double-barrel shotgun, ammunition, luxury clothing and leather goods, cash, jewellery and six vehicles.[1] France-Antilles lists the same follow-on seizures as a category-B handgun, a double-barrel shotgun with various ammunition, a 900-gram cocaine brick, 20 kg of cannabis herb, luxury clothing and leather goods with jewellery, large cash sums and six vehicles.[2]

Investigators established that at least 15 tonnes of drugs, mainly cocaine and to a lesser extent cannabis, had been transported from Venezuela to Guadeloupe beaches over the previous two years.[1] The sea operation off Dominica was run by Dominican nationals.[1] Because of the scale of the seizure, the Fort-de-France Interregional Specialised Jurisdiction took the case and travelled to Guadeloupe with prosecutors, an investigating judge and a liberty-and-detention judge.[1] The investigation also found money-laundering through fund transfers to Dominica and Venezuela estimated at more than 450,000 euros.[1]
