Calcutta, Sept. 16 :    Calcutta, Sept. 16:  Police have busted a drug gang, which funded various militant organisations, used Calcutta as its base, and whose operations covered a wide swathe from India's troubled north-east to Nepal. Keeping chief minister Buddhadeb Bhattacharjee and the Union home ministry informed about the operation, Central intelligence agencies and state law enforcers have arrested more than two dozen criminals over the past 10 days in Calcutta, Howrah and the districts. 'We strongly believe that the gang raised money by selling drugs and used it to buy arms for various terrorist outfits. The discovery is, indeed, startling,' a senior officer said. Contraband-mainly ganja weighing nearly 200 kg, worth nearly a crore (after refinement), Indian currency notes valued at Rs 250,000 and ready-to-use open tickets of different airlines were seized from the arrested. On condition of anonymity, an officer said the arrested men had a nexus with the Central Reserve Police Force, which enabled them to carry out operations wearing CRPF uniforms and even using official vehicles. 'The gang represents a large chain, each section of which was given a part of the turf to look after', he said. After the first few arrests, Bhattacharjee asked the police to 'get to the bottom of the case' and monitored it personally. Aided by the Narcotic Control Bureau, the law enforcers carried out raids in central Calcutta, Uluberia in Howrah and districts like Murshidabad, Birbhum and Burdwan. One of the arrested men was identified as 'Mondal', who was flushed out from a central Calcutta hide-out. He is suspected to be a conduit for druglords dealing in ganja, cocaine and heroin. Mondal and his henchmen, all wanted in major cases, distributed the drug consignments and collected payments from peddlers in central and north Calcutta. He oversaw the passage of drugs to Bangladesh and Nepal and ran a fake passport racket. B.N. Ramesh, superintendent of police, Burdwan district, said interrogators suspected the arrested to have links with terrorrist organisations like NSCN, Ulfa, Bodo and Kamtapur Liberation Organisation. Some of them purchased weapons like AK 47 and AK 56, rifles, grenades and sophisticated explosives for the organisations. Two suspected agents of the Inter-Services Intelligence of Pakistan were held in Burdwan. Documents and cellphones found on them provided clues to their involvement in drug-trafficking from Dimapur, hub of NSCN activities in Nagaland, to Bengal, Uttar Pradesh and Nepal.
