Containers at various ports across the country are being searched by Customs and DRI officials following a tip-off that fake currency notes were being smuggled into the country in ships.
The searches are being held for the last two days at various ports, official sources said.
"Searches are being conducted at ports across the country. The Customs department is conducting the searches in presence of Department of Revenue Intelligence (DRI) officials," a senior official said.
Replying to a question, the official declined to confirm whether containers that arrived from Pakistan and Sri Lanka were being searched as reported in a section of media, and said, "Containers are being searched."
Two instances of seizure of fake Rs 2,000 currency notes were reported in West Bengal in February, 2017.
