She has been accused of criminal conspiracy and cheating by the CBI for alleged irregularities in a loan of Rs 3,250 crore in 2012 to the Videocon Group, which became a non-performing asset for the ICICI Bank.
A whistleblower alleged that Ms Kochhar's husband Deepak Kochhar and her family members benefited from the dealings.
According to the charges in the case, former Videocon chairman Venugopal Dhoot allegedly invested crores of rupees in NuPower Renewables, a company founded by Mr Kochhar, months after the Videocon group was granted a loan by the bank.
The loan was cleared by a committee of which Ms. Kochhar was a member, alleges the CBI. The agency says she abused her official position and "got illegal gratification/undue benefit through her husband from Dhoot for sanctioning Rs 300 crore to Videocon.
