New Delhi, The Directorate of Revenue Intelligence (DRI) on Thursday said it has recovered a consignment of 52 kg of cocaine valued at Rs 500 crore under "Operation Namkeen" at Mundra port that was imported from Iran.

"On the basis of extensive data analysis and field surveillance, intelligence was developed by the DRI that certain consignments being imported from Iran were likely to contain narcotic drugs.

"... 'Op Namkeen' was launched and a consignment, declared to contain 1,000 bags of common salt having gross weight of 25 MT, which had been imported at Mundra port from Iran, was identified for detailed examination," said a DRI official.
