MUMBAI, Aug. 14 -- The Narcotics Control Bureau (NCB) has seized narcotic and psychotropic substances including opioid-based medicines and charas worth Rs.2.20 crore, in two separate intelligence-led operations against alleged inter-state drug trafficking networks. Two alleged drug peddlers from whom a large chunk of narcotic substances were seized have been arrested, sources in the NCB told Hindustan Times. In the first case, the NCB's Mumbai zonal unit on Saturday seized 1,080 bottles of Codeine-based cough syrup (CBCS) from an alleged peddler identified as 'NS', who was placed under arrest. During interrogation, the accused revealed that the bottles had been brought from Gujarat to the city on a passenger train and they were meant to be sold in retail stores across Mumbai, Bhiwandi and adjoining areas. Based on information provided by the accused, an NCB team raided the godown of a Vadodara-based alleged CBCS distributor and seized another 13,398 CBCS bottles and 12,240 tablets of Tramadol, with the total value of the seizure estimated at Rs.2 crore. During investigation, the NCB learnt that 'NS', who primarily operated from Bhiwandi in Thane district, had been arrested by the Maharashtra police earlier in a case under the Narcotic Drugs and Psychotropic Substances (NDPS) Act. The Vadodara-based distributor, from whose premises the NCB seized CBCS bottles and Tramadol tablets, was a wanted accused in the NDPS case, NCB officials said. In the second operation, the NCBs' Mumbai unit on Wednesday seized 1.06 kilogram of charas, worth Rs.20 lakh, from the Ghatkopar residence of a suspect identified as 'AS'. During interrogation, 'AS' said that keeping the upcoming festive season in mind, she and her associates had procured the charas for sale across the city. The NCB is now trying to trace and apprehend her associates, sources said....
