An internal investigation is underway in Maharashtra's Mumbai into an alleged scam in the Employees Provident Fund Organisation (EPFO) where around Rs 21 crore was allegedly siphoned off using dummy beneficiaries by registering them as employees of defunct or closed companies. Sources in the EPFO said no individual beneficiary account has been targeted but the money has gone out of the pooled fund which will cause loss to the organisation. No case has been registered in the matter yet.
