Rajiv Kochhar, the brother-in-law of ICICI Bank MD & CEO Chanda Kochhar, who was stopped by immigration authorities at Mumbai airport earlier this week when he was to leave for Singapore, was questioned by the CBI for the third straight day on Saturday. Mr Kochhar, who owns a Singapore-based consultancy firm Avista Advisory and is engaged in restructuring loans of companies, was questioned in connection with a preliminary enquiry by the agency to find if any quid pro quo was involved in ICICI bank issuing a Rs. 3,250-crore loan to Videocon Group in 2012.
