Indian Coast Guard Seizes 526 Kg of Drugs in Arabian Sea
The Indian Coast Guard, working with the Gujarat Anti-Terrorism Squad (ATS), has seized around 526 kilograms of narcotic drugs from an Iranian dhow in the Arabian Sea. Five Pakistani nationals aboard the vessel were detained during the operation, according to the Coast Guard and news reports published on September 30, 2026. The seized drugs have an estimated international-market value of more than ₹3,000 crore.
The operation took place west of Lakshadweep after security agencies received intelligence about suspected maritime drug trafficking. Officials said Coast Guard assets used sea and air surveillance to track the suspicious vessel before launching a pursuit and boarding it.
Iranian Dhow Intercepted Near Lakshadweep
According to the Indian Coast Guard, the vessel was an Iranian dhow that was intercepted on September 25. The operation involved continuous monitoring before Coast Guard personnel moved to stop and board the vessel. The location was west of Lakshadweep in the Arabian Sea.
The Coast Guard said the vessel, its crew and the seized narcotics were later escorted to Mumbai under armed security. They were brought to the city for joint questioning and further legal proceedings involving multiple agencies.
The Gujarat ATS also confirmed the detention of five Pakistani nationals in connection with the operation. Authorities are expected to examine the identities of the crew members, the vessel’s route and the suspected supply chain as the investigation continues.
Heroin and Methamphetamine Found
The seized consignment reportedly contained high-grade heroin and methamphetamine. Together, the drugs weighed about 526 kilograms. Authorities estimated their value at more than ₹3,000 crore in the international market.
The high valuation reflects the estimated international-market worth of the seized narcotics and should not be interpreted as a confirmed retail value in India.
The seizure is significant because methamphetamine and heroin are both controlled substances that are trafficked internationally through different routes. Maritime trafficking can make enforcement more difficult because vessels can travel long distances and change routes before reaching coastal areas.
How the Coast Guard Detected the Vessel
The operation highlights the role of intelligence-led maritime surveillance.
Officials said the Coast Guard received actionable intelligence and then used sea-air surveillance to track the suspicious dhow. Such operations can involve aircraft and ships working together to maintain information on a vessel’s location and movement before an interception is attempted.
After the vessel was tracked, Coast Guard personnel launched a pursuit and boarded it at sea. The operation demonstrates how maritime agencies can combine intelligence, surveillance and boarding teams to investigate suspected trafficking activities.
The authorities have not publicly released all details about the original intelligence input or the suspected intended destination of the drugs.
Drugs and Vessel Brought to Mumbai
Following the interception, the dhow, its crew and the seized narcotics were taken to Mumbai. The Coast Guard said the material would be subject to further investigation and legal proceedings.
Bringing the vessel to a major port allows investigating agencies to conduct detailed inspections, document the seized material and question the detained crew.
The next stage of the case is expected to focus on establishing where the drugs came from, who was expected to receive them and whether other people or organizations were involved.
Detention at this stage does not by itself establish criminal guilt. The allegations and evidence will be examined through the applicable legal process.
Growing Focus on Maritime Drug Trafficking
The latest seizure comes amid continued concern among Indian authorities about international drug trafficking through maritime routes.
The Arabian Sea connects major shipping and trading routes, and security agencies regularly monitor vessels operating in the region. Maritime interdiction operations can play an important role in preventing large consignments of narcotics from reaching coastal locations.
The Coast Guard said the latest operation was aimed at disrupting transnational drug trafficking and preventing illegal narcotics from reaching the Indian mainland.
The operation also shows the importance of cooperation between central maritime agencies and state-level enforcement bodies. In this case, the Indian Coast Guard and Gujarat ATS worked together on surveillance, interception and subsequent investigation.
Investigation Continues
Authorities are expected to carry out a detailed investigation into the five detained Pakistani nationals and the Iranian vessel.
Investigators may examine the vessel’s ownership and registration, communications, financial links, travel records and possible connections with international trafficking networks. The seized narcotics will also undergo forensic and legal examination.
Officials have not yet publicly disclosed the full network behind the shipment, and the investigation is ongoing.
Why the Seizure Matters
The seizure of 526 kg of narcotics worth more than ₹3,000 crore represents a substantial interception of an alleged maritime drug shipment. It also illustrates the increasingly important role of surveillance technology and coordinated operations in monitoring India’s maritime zones.
For investigators, the seizure of the drugs and vessel provides physical evidence that can be examined as the case develops. The identities and roles of the detained crew members will have to be established through investigation and due legal process.
Conclusion
The Indian Coast Guard and Gujarat ATS have seized approximately 526 kg of heroin and methamphetamine from an Iranian dhow in the Arabian Sea and detained five Pakistani nationals aboard the vessel. Authorities estimate the seized narcotics are worth more than ₹3,000 crore in the international market.
The operation began with intelligence-led sea and air surveillance before the vessel was pursued and boarded west of Lakshadweep. The dhow, crew and contraband were later escorted to Mumbai for further questioning and legal proceedings.
The case remains under investigation, and further details about the suspected trafficking network are expected as authorities examine the vessel, the narcotics and the detained crew.
