Based on specific intelligence that Mephedrone (a psychotropic substance under the NDPS Act, 1985) was being smuggled from Hyderabad to Mumbai in substantial quantities by two passengers traveling on a bus, officers set up surveillance overnight and intercepted both individuals in the early hours of December 3.

A search of their baggage led to the recovery of 16 kg of a white powdered substance, believed to be Mephedrone, valued at approximately Rs 24 crore in the illicit market. Preliminary testing confirmed the substance as Mephedrone.
