The Central Bureau of Investigation is tightening the screws on the infamous ICICI Bank-Videocon loan case. Just 3 days after the shock arrest of Chanda Kochhar and her husband, CBI today took Videocon Group chairman Venugopal Dhoot into custody this morning. The founder of the cash-strapped consumer electronics major was arrested for not cooperating with the agency. It is more than the winter chills sending shivers down the spine of business barons and powerful bankers across India. Just when everyone thought the ICICI Bank loan saga had got lost in the labyrinth, the CBI nabbed Chanda Kochhar last Friday… following it up this morning by netting an even bigger fish - Videocon Group Chairman Venugopal Dhoot. The two high-profile arrests have renewed attention on the ‘phone-banking’ scandals of the UPA era.
