This came to light after some consignments of fake currency were intercepted by security agencies and during interrogation of people involved in the racket it was found that counterfeiting of Rs 1,000 was costlier than notes of lesser denominations, official sources said.
According to a report by Central Economic Intelligence Bureau (CEIB), India is "extremely vulnerable" to FICN from Nepal, Bangladesh, Malaysia and Thailand through Pakistani operators and their conduits.
Intelligence assessments and seizure reports confirm that India is extremely vulnerable to FICN from Nepal, Bangladesh, Malaysia and Thailand. "Pakistani operators based in Nepal, Bangladesh, Malaysia and Thailand act as recipient of FICN from Pakistan as well as conduits to the distribution channels in India through air and land border," the report said.
Seizure reports also indicate FICN racketeers using villages, weekly haats, liquor shops and petrol pumps of the border areas with Nepal and Bangladesh to pump the fake currency into the system, it said.
