Kolkata: Kolkata Police has seized drug and narcotics worth Rs 12 crore in past five days, which made the police lose sleep over the newly emerged market for narcotics racketeers where students are the targeted customers.During the past few months Special Task Force (STF) of Kolkata Police arrested several drug and narcotics racketeers and came to know that maximum number of their customers are students from various educational institutions across the city. During the probe, investigators came to know that drug and narcotics elements are entering India through Myanmar border. It has been the corridor for such illegal trade since a long time to deliver the drugs and other narcotics elements to Bangladesh. Even after trouble cropped up in North East, narcotics racketeers are still using the same area to smuggle in the drugs but changed the corridor to deliver those to Bangladesh using Kolkata and a few other Bangladesh adjacent districts of Bengal. As a result a market for such illegal trade has emerged in Kolkata during last few years. According to police sources, earlier only rave parties and night clubs were the place where usually drugs and narcotics were used to be sold. After police came to know about such activities, several raids were conducted in late night parties and several persons were apprehended with drugs and narcotics elements. Since then such activities were controlled and supply of drugs and narcotics elements gone down a lot. According to police sources, during the past few months, STF personnel have arrested several narcotics racketeers with huge quantity of such elements and came to know that they are targeting students of educational institutions in the city. During a detailed probe police found that Amphetamines commonly known as ‘Yaba’ in tablet form is the most popular narcotic element among the youths as it is quite cheaper than the other narcotic elements. However, police are trying to create awareness and suggesting authorities of educational institutions across the city to arrange councelling sessions for their students in order to save the students from the clutches of drugs and narcotics elements. “We are concern about the illegal trade. Vigilance has been stepped up to prevent such trade,” said a senior Kolkata Police official.
