The arrest of ICICI Bank's former CEO Chanda Kochhar's husband Deepak in the ICICI-Videocon loan fraud case is "illegal" and "needs to be explained", the lawyer representing him has said. "My client was arrested in an inhumane manner at a time when his son's marriage has been fixed," he added. Deepak, Chanda and Venugopal Dhoot are in 3-day CBI custody.
