Sewers Used as Drug Stash: Two Arrested by ADSU in Rose-Belle

Anti-drug officers in the south of Mauritius have made an unusual discovery — a drug cache hidden inside a sewer drain — after arresting two suspects in the Rose-Belle area. The arrests were carried out by the Anti-Drug and Smuggling Unit (ADSU), the Mauritius Police Force's specialist division responsible for investigating and combating drug trafficking across the island. The Rose-Belle ADSU unit led the operation. According to the report, the two suspects had been using the sewage network as a concealed storage point for drugs — a method designed to avoid detection during routine searches of homes or persons. Investigators discovered the narcotics hidden within the drain infrastructure before apprehending the individuals. The specific substances seized, the quantities involved, and the identities of the suspects have not been disclosed at this stage, as the investigation is ongoing. **An evolving tactic in Mauritius's drug trade** This case highlights the increasingly creative methods used by drug traffickers in Mauritius to hide narcotics from law enforcement. Authorities have previously found drugs concealed in vehicles, parcels, household items, and even on boats — but the use of sewer infrastructure as a cache represents a notable escalation in concealment tactics. Rose-Belle is a town in the Grand Port district in the south-east of Mauritius, a region that ADSU units have been actively monitoring as part of broader national anti-drug operations. **What this means** For residents and communities, the discovery is a reminder that drug networks adapt constantly to evade police. The ADSU's ability to uncover hidden caches in non-obvious locations — such as underground drainage systems — reflects the increasingly sophisticated surveillance and intelligence work being carried out by Mauritian anti-narcotics forces. Mauritius recorded 1,560 drug cases and over Rs 1.3 billion worth of seizures in 2026 alone, underlining the scale of the challenge facing law enforcement. Cases like this one, where traffickers resort to concealing drugs in public infrastructure, suggest that pressure from police is forcing networks to take greater risks. The two suspects are expected to be charged in connection with drug possession and/or trafficking offences under Mauritian law. Further details are likely to emerge as the case progresses through the justice system. Source: Le Defi Media
