Rs 52 crore of the Rs 230 crore that DMK-controlled Kalaignar TV repaid to 2G accused Shahid Balwa came from 19 Kolkata-based firms with fictitious addresses that are not traceable, senior tax officials told the Joint Parliamentary Committee on telecom on Wednesday. The payment is part of the Rs 200 crore suspected kickback for 2G licences but which Kalaignar TV says was a loan received from DB Realty through two other firms -- Cineyug and Kusegaon Fruits and Vegetables.
