Customs and the National Narcotics Agency uncover hidden drug laboratory in Bali; two Russian nationals arrested
Customs and the National Narcotics Agency (BNN) have exposed a clandestine drug laboratory in Gianyar Regency, Bali. In a joint operation, officers seized two Russian nationals suspected of producing mephedrone at a villa in the area. The operation underscores Indonesia’s ongoing crackdown on drug production and trafficking and ties into government efforts to curb narcotics circulation.
Customs’ Director of Drug Interdiction, R. Syarif Hidayat, said the discovery demonstrates the importance of monitoring cross-border goods, including shipments that can be used as drug precursors. ‘The seizure of a clandestine lab is a tangible demonstration of Customs’ commitment to protecting the public from narcotics. The monitoring extends not only to finished drugs but also to chemicals and equipment that could be used to produce them,’ he said.
The case began on 21 January 2026 when Soekarno-Hatta Customs intercepted a shipment from China destined for Uluwatu, Bali. The package contained two bottles of liquid believed to contain valerophenone and 4’-methylpropiophenone, chemicals that can be used in drug production. This finding triggered a joint task force involving the Customs Directorate of Drug Interdiction, the Bali, NTB, and NTT Customs offices (collectively referred to as Bali Nusra), and Soekarno-Hatta, working with the BNN. The team conducted information gathering and surveillance on movements of shipments from 28 January to 5 March 2026.
‘From analysis and development, we identified multiple shipments of laboratory equipment and chemicals, both domestic and foreign, entering via Soekarno-Hatta and Ngurah Rai airports. The items are believed to support drug production at a villa in Bali,’ Syarif said.
On 6 March 2026, the joint team carried out an arrest at Vila The Tetamian in Bali, detaining a Russian woman identified as NT. A search of Vila The Lavana De’Bale Marcapada, suspected to be the production site, followed. At the location, officers found a variety of chemicals in powder and liquid forms, as well as mephedrone. Concurrently, a Russian man identified as ST was arrested at Vila Rena’s Kubu; a liquid chemical suspected to be related to drug production was found at the site.
The operation yielded a range of evidence including 644 grams of crystalline mephedrone, about 7,250 millilitres of semi-processed mephedrone, 2,600 grams of solid chemical precursors, and 219,780 millilitres of liquid chemicals. Investigators also recovered 36 laboratory equipment items used in drug production.
‘Safety of the public depends on breaking the chain of production and distribution,’ Syarif added. The partnership between agencies, he said, is crucial in tackling increasingly complex and transnational drug networks. By maintaining integrated surveillance over shipments, chemicals, and laboratory equipment, authorities hope to narrow the space in which drug networks can operate and shield communities from harm.
