NAVI MUMBAI, March 17 -- The Anti-Narcotics Cell (ANC) of the Navi Mumbai police has arrested three men from Punjab and seized high-grade heroin, an Austria-made Glock pistol, live cartridges and a trailer truck in a case investigators believe may be linked to a cross-border narcotics supply chain that uses drones to smuggle drugs into India before routing them into Maharashtra. The accused, Baljit Singh Savinder Singh alias Monu, Gurupratap Singh Sharanjit Singh alias Gopi, and Karamjit Singh Nindar Singh, all residents of Amritsar in Punjab, were apprehended during an operation in the Chakan MIDC-Nigoje village area of Pimpri-Chinchwad in Pune district last week. A court has remanded the trio to police custody till March 18. Police said the arrests were made during a parallel investigation conducted by the Taloja police station in connection with a narcotics case registered last year under the Narcotic Drugs and Psychotropic Substances (NDPS) Act, 1985. "During the probe, it was found that wanted accused Baljit Singh and his associate Gopi were trafficking narcotic substances to Navi Mumbai, Mumbai and Pune using a trailer truck that entered Maharashtra via Madhya Pradesh. A team was assigned to track their movements," said Dharmpal Bansode, assistant commissioner of police. Acting on technical surveillance and intelligence inputs, police tracked the suspects' truck from Nashik before intercepting it in Pune district. During the operation, officers seized 82.6 grams of high-grade heroin valued at Rs.41.30 lakh, an Austria-made Glock pistol worth Rs.8 lakh, two magazines, four live cartridges worth Rs.2.5 lakh, a trailer truck valued at Rs.50 lakh, four mobile phones and a weighing scale. The total value of the seized contraband and property is estimated at Rs.1.03 crore. Police said they are searching for 14 more individuals believed to be part of the supply network. So far, six offences linked to the suspected interstate drug racket have been registered, with 40 accused arrested and contraband and property worth nearly Rs.6 crore seized. More recently, in February, Navi Mumbai police arrested Surinder Gurujant Singh alias Kalu, 24, and Maninder Gurujant Singh, 27, both residents of Punjab, during a raid in Taloja and seized 118 grams of heroin and 143.6 grams of opium....
