The CBI has submitted a chargesheet against Nalini Chidambaram, wife of former Union finance minister P. Chidambaram, in the Saradha default scam in Bengal.

The chargesheet was filed in the special CBI court in Barasat near Calcutta on Friday.

According to the document, Nalini Chidambaram, a Supreme Court lawyer, had allegedly conspired with the chairman of the Saradha Group, Sudipta Sen, in misappropriating depositors’ funds.

The CBI alleged that Manoranjana Sinh, the estranged wife of former Union minister Matang Sinh, introduced Sen to Nalini to manage probes by various central agencies like the Securities and Exchange Board of India (Sebi) and Registrar of Companies. The chargesheet said Nalini had received Rs. 1.4 crore during 2010-12 through Sen’s companies.

Thousands of people in Bengal had invested in schemes floated by the Saradha Group before it stopped repayment of the promised amounts.

The scam surfaced in 2013 when complaints of default and non-payment started pouring in against the Saradha Group. Initially, the case was registered with the police before the CBI took over.

The central agency had submitted several chargesheets in the case before. The chargesheet against Nalini is the sixth one in the Saradha scam.

Earlier, Nalini had been questioned by the Enforcement Directorate that is probing the money laundering angle in the Saradha scam.
