Days after the nearly 6,000 kg of methamphetamine were seized from a trawler in Andaman and Nicobar Islands, investigators found that the smugglers had made multiple calls to their contacts in South East Asian countries, including one person in north India, a top police officer said on Friday. They also entered navigational coordinates for Neil Island in South Andaman and Rangat in Middle Andaman into their systems. Andaman and Nicobar Police collaborated with the Indian Coast Guard to arrest six international narco cartel members of Burmese origin and seize their boat customised for Narco transhipment. Dhaliwal said, “Apart from making calls to people in South East Asian countries, the smugglers also contacted a person in North India. We have alerted the agencies concerned and are looking into details about this person.” As part of the investigation, the police are trying to find out who bought the Starlink internet device the smugglers were using and its usage history, he said.
