Guwahati: The Narcotics Control Bureau (NCB) has achieved a major breakthrough in its sustained crackdown against transnational drug trafficking networks operating along the India–Myanmar border with the arrest of key Myanmar-based trafficker Thancintuang @ Chintuang @ Tluanga from Delhi following extensive surveillance, intelligence development, coordinated interstate coordination, and sustained follow-up operations.Chintuang has emerged as one of the most significant traffickers operating along the Myanmar–Mizoram–Manipur–Assam–Tripura corridor and has been identified as a major international supplier of Methamphetamine and Heroin operating from Myanmar. Investigations revealed his extensive involvement in organizing cross-border trafficking networks routing narcotic consignments through Mizoram, Manipur, Assam, and Tripura into various parts of India and Bangladesh. He was wanted in multiple NDPS cases registered by NCB and several Drug Law Enforcement Agencies (DLEAs), including two cases registered by NCB.Further investigation revealed that Chintuang was also accused in two NDPS cases registered by Champhai Police in 2025 relating to suspected trafficking of Methamphetamine and Heroin. He was additionally found involved in six NDPS cases registered by the Mizoram Excise & Narcotics Department in 2023 linked to heroin trafficking activities. Investigations indicate his involvement in illicit drug trafficking networks valued at approximately Rs115 crore. He is linked to seven NDPS cases connected with the Myanmar–Mizoram–Tripura/Assam corridor and is also suspected in five additional cases associated with the Myanmar–Manipur–Assam route.Also read | Delhi advises 2-day work-from-home in private sector, car pooling to conserve fuelChintuang was the prime accused in a 2024 NCB Agartala Zone case involving seizure of 14 kg Methamphetamine and 2.8 kg Heroin, in which his arrest marks the seventh apprehension. He was also the prime accused in another NCB Agartala Zone case of 2025 involving seizure of 49.1 kg Methamphetamine tablets, where nine traffickers had already been arrested prior to his apprehension.During the investigation, several members of the syndicate and close associates of Chintuang were identified and apprehended by NCB. Among them, Vungkhanthawna, identified as a close associate and key facilitator, played a major role in coordinating movement and delivery of narcotic consignments linked to the Myanmar-based trafficking network. He was arrested during follow-up operations and was also found involved in another NDPS case registered by Mizoram Police. Considering his continued involvement in illicit trafficking activities, proceedings under the PITNDPS Act were initiated against him.Another associate, Lalrampari, functioned as a major hawala operator responsible for handling and channelling proceeds generated through illicit drug trafficking activities of the syndicate. She was arrested by NCB on 08.08.2024. Investigation revealed hawala transactions amounting to nearly Rs 100 crore linked to the network, following which the matter was shared with the Enforcement Directorate (ED). Properties suspected to have been acquired through proceeds of drug trafficking were also frozen by competent authorities.Further investigation led to the arrest of Abu Saleh @ Saifuddin from Cachar, Assam, on 20.11.2025. He was identified as a major Indian operative and logistics coordinator associated with Chintuang’s network and was actively involved in transportation and distribution of narcotic substances across the Assam corridor. He was found linked to multiple NDPS cases registered by Mizoram Police and the Mizoram Excise & Narcotics Department.Also read | Wayanad landslide survivors begin moving into Kalpetta townshipOne of the key accused arrested in the 2025 Agartala Zone case was Jabrul from Karimganj, Assam, another significant associate connected to Chintuang’s transnational trafficking network. He was apprehended on 03.12.2025 along with an additional consignment of narcotic drugs. Investigation revealed his active role in interstate trafficking operations and coordination of drug movements through the Tripura–Assam route. He was also found involved in multiple NDPS cases registered by Tripura Police and NCB.Financial investigation in the cases led to identification and temporary freezing of multiple bank accounts linked to the accused persons having substantial suspicious transactions connected with drug trafficking proceeds. NCB has initiated comprehensive 360-degree financial investigations against drug syndicates to identify and attach assets generated through illicit trafficking. Properties, bank accounts, and financial proceeds linked to drug trafficking networks are being identified and frozen under provisions of the NDPS Act and the Prevention of Money Laundering Act (PMLA) to dismantle the financial ecosystem sustaining organized narcotics trafficking.Investigation in both cases revealed the existence of a highly organized interstate and international drug trafficking network extending from Myanmar to Mizoram, Manipur, Assam, Tripura, and Bangladesh. The syndicate utilized multiple trafficking routes, local facilitators, transport coordinators, hawala channels, and financial handlers for smuggling and distribution of Methamphetamine and Heroin across international and interstate borders. Through sustained intelligence development, coordinated interstate action, and continuous follow-up operations, NCB successfully identified and arrested major operatives connected to these transnational cartels, including the latest arrest of Chintuang, the key Myanmar-based supplier.The arrest reflects NCB’s relentless and intelligence-driven strategy of targeting major drug kingpins operating in the North Eastern Region, including those attempting to operate from outside India. Since 2025, NCB has intensified its network-centric investigations by adopting both “top-to-bottom” and “bottom-to-top” approaches aimed at dismantling entire syndicates rather than merely intercepting consignments.The arrest of Chintuang marks the second major Myanmar-based drug supplier secured by NCB in 2026 and another major success in NCB’s sustained crackdown against organized transnational drug trafficking networks operating along the India–Myanmar border. In the North Eastern Region alone, NCB registered 48 NDPS cases during 2025, resulting in the arrest of 116 drug traffickers and seizure of substantial quantities of narcotic drugs valued at approximately Rs 665 crore in the illicit drug market. In 2026, NCB has already registered 31 NDPS cases so far, resulting in the arrest of 54 drug traffickers and seizure of substantial quantities of narcotic drugs during sustained enforcement operations across the region.These achievements reflect the intensified enforcement strategy and operational success achieved by NCB NER in targeting organized interstate and transnational drug trafficking syndicates operating through India–Myanmar border routes. The successful operations highlight NCB NER’s continued commitment towards dismantling entire drug supply chains, including international suppliers, transport coordinators, hawala operators, financiers, and local distribution networks. These sustained actions have significantly strengthened the fight against organized narcotics trafficking in sensitive border regions and contributed towards safeguarding national security and public health.NCB has intensified enforcement activities along the India–Myanmar border through enhanced intelligence-sharing, inter-agency coordination, and advanced surveillance techniques, resulting in multiple major seizures and arrests in recent years. The Narcotics Control Bureau reiterates its firm resolve to eliminate drug trafficking and urges public cooperation in reporting suspicious activities related to narcotics.
