Three companies - Unitech, Swan Telecom and Reliance Telecom - have  also been named in the formal charges filed by the Central Bureau of Investigation (CBI) April 2 before the special court of the probe agency presided over by Judge O.P. Saini.

Raja and his team of men from the Department of Telecom (DoT) face  charges of conspiracy. The former minister also faces forgery charges. Chandolia and Behura have been accused of misusing official position.

He was arrested by the probe agency in the national capital Feb 2,  along with Behura and Chandolia, while Balwa was arrested from Pune on Feb 8.
