Malda in West Bengal was always the capital for counterfeit notes smuggled in from bordering Bangladesh. Demonetisation had brought the business to a standstill. But in a worrying development, the fake notes are back. In the last three weeks, around Rs. 4 lakh worth of fake 2,000 rupee notes were seized by the Border Security Force or BSF. What is worrying is the quality of the fakes as they seem to look very close to the new notes introduced just three months ago. NDTV travelled to Malda and found that the BSF has stepped up vigil to stop the smugglers.
