Clamping down on entities running dubious investment schemes, the Government has asked SFIO to probe at least six more such cases in last four months alone. The Serious Fraud Investigation Office (SFIO), which comes under the Corporate Affairs Ministry, is now probing more than 140 cases pertaining to fraudulent money pooling activities. The probe agency has been directed to investigate at least six more cases where money is believed to have been collected illegally in the name of chit funds since mid-July this year. “A total of 139 so called 'chit fund' cases have been assigned to SFIO till July 13, 2015, for probing as well as 6 more cases have been assigned to it since that date,” the Ministry told a house panel recently. The ministry's submission was made to the house panel on finance that looked at the efficacy of regulation of collective investment schemes. Despite multiple regulations in place at both state and central levels, there have been rising instances of people getting duped by fraudulent money accumulating plans that promise high returns in a short period of time.
