agency probe into India's 2G spectrum scam appeared to make some headway, the sudden death of Sadiq Batcha comes as a setback to the investigation process. Thirty-seven-year-old Batcha's phenomenal rise from a small-town salesman to a real estate tycoon is more than just a rags-to-riches story, writes the Times of India in its editorial. Excerpts: From the available evidence, his rise can be linked to the political fortunes of former telecom minister A. Raja, currently under investigation in the 2G spectrum scam case. Batcha's real estate firm, Green House Promoters – with Raja's kith and kin holding crucial positions – started with an equity base of Rs1,00,000 (about $2,300) in 2004 and went on to become a company worth billions of dollars within a short time. The firm is alleged to be one of the vehicles used to launder kickbacks from the sale of 2G spectrum licences. As a key aide and business associate of Raja, Batcha was a crucial link to any investigation unearthing the money trail associated with the telecom scam. Reports suggest that Batcha was ready to turn approver in the case, and his death raises many questions. Opposition parties, both at the Center and in Tamil Nadu, suspect foul play and an attempt to subvert the investigation process. Their demand for a thorough probe into the death is justified. On its part, the state government has indicated its willingness to do so. A political consensus in this regard is welcome. __
