DRI seizes massive 137 kg consignment of crystal meth; busts coastal drug trafficking network; 4 arrested in Tamil Nadu

The Directorate of Revenue Intelligence seized a gross 137 kg consignment of crystal methamphetamine. Officers found it in a coastal village in Nagapattinam district, Tamil Nadu, during an operation conducted from 16 to 17 October 2026. The seizure targeted a suspected network preparing to move the drug onward to Sri Lanka.

The consignment was packed in six duffel bags. Those bags contained 27 silver-foil packets, each weighing about 5 kg. A simultaneous search at a suspected organiser’s premises also recovered Rs. 10 lakh in cash. Officers seized two four-wheelers and one two-wheeler allegedly used to transport the substance.

Four people were arrested under the Narcotic Drugs and Psychotropic Substances Act, 1985. They were remanded to judicial custody. The operation also exposed people involved in organising coastal export, transportation, storage, and logistics for the consignment.

Crystal methamphetamine is a synthetic stimulant drug. It can strongly affect the brain and nervous system, producing intense alertness and energy. It also carries a high risk of dependence and serious physical and mental health damage. The article describes the seized substance as suspected high-purity methamphetamine and identifies it as a banned synthetic drug.

Its legal status reflects those risks. In India, methamphetamine is controlled under the Narcotic Drugs and Psychotropic Substances Act, 1985. The law restricts unauthorised possession, transport, sale, and trafficking. In this case, DRI officers seized the substance under that Act after finding it in silver-foil packets stored near the coast.

The article does not detail the drug’s medical effects or legal scheduling. These points use established public-health and legal knowledge. The case shows why authorities treat large methamphetamine consignments as a serious organised-trafficking threat, rather than an ordinary transport offence.

The DRI recovered 137 kg gross of crystal methamphetamine. The article estimates its value at more than Rs. 100 crore in the illicit drug market. This makes the seizure one of the biggest narcotics seizures in Tamil Nadu’s coastal region in recent years, according to the release.

The scale is visible in the packaging and logistics. Officers found six duffel bags holding 27 silver-foil packets, each weighing approximately 5 kg. The operation also uncovered Rs. 10 lakh in suspected sale proceeds, two four-wheelers, and one two-wheeler. These details show that the consignment required storage, transport, and planned onward movement.

The value signals the potential financial importance of the shipment to the trafficking network. It also explains the intelligence-led response and the focus on dismantling the network. The operation removed a substantial quantity from illicit circulation before the planned maritime movement could occur.

The suspected network planned to smuggle the narcotic consignment to Sri Lanka by sea. The article says the shipment was intended to move through a mid-sea transfer. This indicates a handover or movement between vessels offshore, rather than a direct land crossing or ordinary port shipment. The release does not identify the vessels or the exact location.

The DRI first received intelligence that a large consignment had reached a coastal location in Nagapattinam district. Officers then conducted surveillance and enforcement operations from 16 to 17 October 2026. They searched the storage site and recovered six duffel bags containing 27 packets of suspected methamphetamine.

Stopping the drugs before the offshore stage prevented the planned maritime export described in the release. The seizure also exposed the network’s coastal export, transport, storage, and logistics roles. Details about the intended receiving vessel, crew, or precise handover procedure are not provided.

The Directorate of Revenue Intelligence, or DRI, is India’s specialised agency for gathering intelligence and enforcing laws against customs-related violations, including illicit trade. In this case, DRI officers acted on specific intelligence, conducted surveillance, searched the coastal location, and seized the suspected methamphetamine and related property.

The Narcotic Drugs and Psychotropic Substances Act, 1985, is India’s main law controlling narcotic drugs and psychotropic substances. The article states that the contraband was seized under this Act. It also says four people were arrested under its provisions and later remanded to judicial custody.

Together, the agency and law enabled both the operational and legal response. DRI investigators identified the suspected route and network. The NDPS Act provided the statutory basis for seizure and arrests. The article does not state the specific charges or sections applied to each arrested person.

The suspected trafficking network faced arrests and the loss of its shipment. Four people were arrested under the NDPS Act, 1985, and remanded to judicial custody. The DRI also seized Rs. 10 lakh in cash, suspected to represent sale proceeds, along with two four-wheelers and one two-wheeler.

The operation affected several parts of the alleged network. The release says it exposed people involved in organising coastal export, transportation, storage, and logistics. Recovering the drugs at their coastal storage point prevented the consignment from reaching the planned maritime route to Sri Lanka through a mid-sea transfer.

The immediate consequence was that 137 kg of suspected crystal methamphetamine was removed from illicit circulation. The broader result was disruption of the network’s organisation and assets. The article reports arrests and judicial custody, but it does not state the eventual trial outcome, convictions, or sentences.

Organised drug trafficking usually separates tasks to reduce the burden and risk carried by any one participant. Organisers arrange money, contacts, timing, and routes. Transporters move the consignment. Storage handlers keep it concealed until movement is ready. Maritime logistics providers arrange boats, crews, offshore coordination, or a transfer point.

The article describes those broad functions in this case. It says the network included people involved in organising coastal export, transportation, storage, and logistics. DRI found the drugs at a coastal storage location, seized vehicles allegedly used for transport, and linked the shipment to a planned mid-sea transfer to Sri Lanka.

The division makes a network harder to uncover because each participant may handle only one stage. The DRI operation disrupted several stages together by seizing the drugs, cash, and vehicles and arresting four people. The release does not identify which arrested person performed which role.
