The house was in the Sampene neighbourhood on the outskirts of Quelimane and held 180 kilograms of cannabis sativa within 625.5 kilograms of drugs in total.[1] Sernic said one of those held used the residence as a warehouse and moved drugs onward in very small quantities to Maputo province and South Africa.[2] The Tanzanian tenant denied knowledge of the drugs, saying his business was buying fish, especially crab, to export to Tanzania for onward sale to China.[1]

The same residence also yielded 440 kilos of heroin intended for trafficking.[3] The same house also held 5.5 kilos of morphine alongside the cannabis.[3] Sernic said the heroin had come from Tanzania.[2] Citing United Nations drug-office figures for East Africa, the authorities put the goods at at least 11 million euros, noting the price varies and multiplies toward the consumer.[3]

Sernic said Quelimane, a city near the Indian Ocean coast and capital of Zambezia province, was serving as a reception and distribution centre for a trafficking network.[3] Sernic said investigations were continuing into links to other criminal networks.[3] Mozambique is described by international organisations as a corridor for international drug trafficking.[3]
