In a written reply to Lok Sabha, Minister of State for Corporate Affairs Arjun Ram Meghwal said the ministry ordered investigation by SFIO in 233 cases between 2012-13 and 2017-18 (till July).
The cases were related to ponzi, chit fund and multi- level marketing activities.
"No money in these cases has been restored back to the investors," the minister said.
The ministry ordered probe by Serious Fraud Investigation Office (SFIO) on complaints of serious nature involving companies which have defaulted after raising money from the public.
