Mumbai - Demonetisation has troubled the common man, but it has apparently brought some relief for city cops. The Samta Nagar police station in Kandivali has seen a sharp drop in criminal activities in its area. Criminal activities have decreased since the demonetisation bullet has been fired. A senior Inspector from the Samta Nagar police station told Mumbai Live on condition of anonymity, "Criminal files are nowhere to be seen since demonetisation." Collateral benefits?
