Raja favoured Swan, Unitech, says CBI in court.....

New Delhi: Former Telecom Minister A Raja and two of his aides - Siddharth Behura and RK Chandolia - have been sent to five-day police custody by a court in Delhi.

Mr Raja was brought to the court amid hundreds of camera crews. He spent the night at the CBI headquarters, where he was arrested yesterday after hours of interrogation. (Read: Ex-Telecom Minister Raja, 2 aides arrested)

Mr Raja was dressed in a gray jacket and stepped out of a white car surrounded by security guards who helped him pave his way through the crowds to enter court.

In court, the CBI said the former Telecom Minister favoured Swan Telecommunications and Unitech and changed spectrum allocation rules last minute.

Mr Raja is accused of masterminding India's largest-ever scam. He allegedly violated government guidelines when he was the Telecom Minister in 2008 to benefit a few telecom operators when 2G spectrum was being allocated for mobile network licenses. The sum of the mistakes made by Mr Raja, according to the government's auditor, could total Rs. 1.76 lakh crore.

In Chennai, the senior-most leaders of his party, the DMK, met and passed a formal resolution expressing their support for Mr Raja. "Just because he has been arrested doesn't mean he's guilty," said the DMK. (Watch: Kanimozhi on DMK's resolution of backing A Raja)

The DMK clarified that for now, Mr Raja will continue in his position as the Propaganda Secretary of the DMK.

The DMK chief and Tamil Nadu Chief Minister, M Karunanidhi, has said in the past that the party will take action against Mr Raja, a massively popular Dalit leader, when and if he is found guilty.

After his arrest, party sources said that the corruption charges against Mr Raja were unlikely to matter much to rural voters, who are not interested in the 2G scam.

In December, the DMK organized a series of public rallies to project Mr Raja as a deserving leader.

Mr Raja's arrest, months before Tamil Nadu votes for its next government, has been a windfall for the Opposition. J Jayalalithaa, who is the leader of the AIADMK, has wasted no time in targeting the DMK and the Centre for trying to cover up the corruption within its ranks.
