A joint operation by Manipur Police, the Narcotics Control Bureau (NCB) and the Directorate of Revenue Intelligence (DRI) has led to the arrest of a woman identified as a key figure in a methamphetamine and heroin pipeline running from Myanmar through the Northeast into Bangladesh. The arrest, made this week, is the third in a documented five-month sequence of arrests tied to the same trafficking network — a pattern that points to a deliberate, staged NCB strategy rather than a one-off bust.
The suspect, identified as Nengzatuan — also referred to in police communications as Nengjatuan, alias Tuanpi — was picked up from a hotel in Churachandpur during a 36-hour, statewide anti-narcotics push that authorities say followed months of intelligence gathering and technical surveillance. She is a resident of Haichin in Myanmar’s Chin State and was wanted in multiple cases under the Narcotic Drugs and Psychotropic Substances (NDPS) Act. Manipur Police confirmed the arrest directly in a post on its official X account on July 22, describing her as “a major drug supplier” wanted in multiple NDPS cases with NCB, DRI and Manipur Police — corroborating, without contradiction, the detail reported by NorthEast Now and The Tribune.
Investigators allege she operated as one of the principal suppliers on the Myanmar side of the border, running a network that moved methamphetamine and heroin through Manipur, Mizoram, Assam and Tripura before the drugs were distributed elsewhere in India and across the border into Bangladesh. Four other people were arrested alongside her in the same 36-hour crackdown, including a Silchar, Assam resident described by police as the network’s principal receiver and coordinator for consignments entering the state, along with three men from Churachandpur and Pherzawl districts in Manipur. Around Rs 2 crore worth of narcotics was seized in that specific operation; officials tied to the wider investigation say the network as a whole has been linked to narcotics and drug proceeds worth more than Rs 53 crore.
Background: this is the third arrest in a chain, not an isolated case. Cross-referencing this arrest against NCB’s own recent case history shows it is not standalone. This arrest followed two earlier, related arrests tied to the same syndicate: Lalhmingsanga in March 2026, and Thancintuang — also known as Chintuang or Tluanga — in May 2026. Officials describe this as a deliberate “network-centric” enforcement approach: rather than seizing a single shipment, NCB has been working up the chain over several months, arresting couriers and coordinators first and using each arrest’s interrogation to move toward the network’s Myanmar-based suppliers. Tuanpi’s arrest fits that sequence as the most senior figure taken into custody so far.
This arrest also sits inside a broader, well-documented shift in how Myanmar-based trafficking operates. Indian officials describe cartels abandoning established smuggling corridors for remote forest and river routes as surveillance has intensified. Unlike the drone-assisted smuggling seen on India’s Pakistan border, the Myanmar route still relies overwhelmingly on human couriers moving contraband on foot, which officials say makes both the smuggling and the investigation slower and more labour-intensive on both sides.
Sentinel NE Desk has not independently verified the Rs 53 crore network valuation beyond what has been attributed to investigating agencies; this figure rests on official statements and has not yet been corroborated by an independent audit or court filing.

How we verified this story
- Confirmed via a second, independent outlet (The Tribune) beyond the original NorthEast Now report: the suspect’s identity, her Chin State origin, and the cross-border, four-state trafficking route.
- Confirmed directly from Manipur Police’s own X account: that an arrest matching this description took place on July 22 and that the individual is wanted in multiple NDPS cases.
- Confirmed via cross-referencing NCB case history: this is the third arrest in a five-month sequence tied to the same network (March and May 2026 arrests preceded it).
- Not independently verified: the Rs 53 crore total network valuation — no independent audit, charge sheet, or court filing found.
- Unclear from public reporting: whether Tuanpi has been formally charged, and whether she or her legal representation has made any statement. No defence-side account found in coverage reviewed.
