A special court in the Indian capital Tuesday granted bail to the country's former Telecom Minister, A. Raja, facing trial for his alleged role in the multi- billion-dollar 2G spectrum scam, after 15 months in jail.

"The bail application is allowed," the Special Judge O.P. Saini said, imposing a condition that Raja has to furnish a bond of 20 lakh Indian rupees (40,000 U.S. dollars).

The special court of the country's premier probe agency, the Central Bureau of Investigation (CBI), also ordered the former telecom minister not to leave the national capital without its permission and not to try to influence any witness in the telecom scam.

Raja, who stepped down as the telecom minister in 2010 following huge uproar from the country's opposition political parties, was arrested by the CBI on Feb. 2, 2011, for allegedly favouring some companies by selling them 2G spectrum air waves at lower rates, thus causing a loss of 40 billion U.S. dollars to the exchequer.

The former minister is the last accused to get bail in the case. Earlier his co-accused got bail.

The CBI has already charged the former Minister and his accomplices and seven corporate heads in the case. The charges include waging criminal conspiracy against the country and cheating.
