The Central Bureau of Investigation (CBI) today, 8 December 2010, raided the residences of former telecom minister A Raja in Delhi and Tamil Nadu in connection with the 2G spectrum allocation scam. The raids are being carried out at the residences of four other telecom officials. Raja was forced to quit as telecom minister last month after a report by the Comptroller and Auditor General (CAG) found him guilty of undervaluing 2G spectrum and circumventing the rules to favour companies who did not meet the eligibility criteria for spectrum licences. The CAG report said that the exchequer had suffered a loss of Rs 1.76 lakh crore in the allocation of 2G spectrum.
