The Central Bureau of Investigation said that post demonetisation, there have been 77 cases related to corruption that have been registered. The CBI said that during the various probes conducted it had been found that the Aadhaar numbers of children were being used to deposit old currency in banks.
Several cooperative banks in Maharashtra and Gujarat" were found to be involved in illegal exchange of notes, the CBI said.
Some individuals had got hold of new currency notes within days of the old notes being scrapped. "Since there were restrictions on individuals in terms of withdrawal of new currency, investigation is on to find out how they could come in possession of such amounts," a statement by the CBI read.
The agency said it had also registered seven preliminary enquiries into the alleged corruption cases. Illegal tender around ₹396 crore had been recovered so far.
The CBI said it received 92 complaints from the general public which reported such illegal exchange in various organisations. "Some private individuals (26) and 21 public servants ( mainly from post office and the banking sector) were nabbed with huge amounts of new currency,'' CBI spokesperson Abhishek Dayal said.
Dayal said the cases related to fraudulent exchange of demonetised notes at commercial banks, co-operative banks, post offices, railways and insurance company.
The CBI claimed that it was ensured that every information related to such violations should be entertained and examined and, if required, cases registered.
The statement further said that "several shell companies were identified during the course of investigations. Concerned law enforcement agencies have been informed of these shell companies for action on their part."
