The homes and offices of former ICICI Bank chief executive Chanda Kochhar and Videocon managing director Venugopal Dhoot were searched by the Enforcement Directorate today in a loan case. The Central Bureau of Investigation has already issued a look-out circular against Ms Kochhar and has revived ones against her husband Deepak Kochhar and Mr Dhoot. Look-out circulars are notices sent to transit points like airports to restrict the movement of people under investigation by probe agencies.
