BJP vice president Mukhtar Abbas Naqvi on Saturday said that the Congress led UPA government is responsible for lower level of corruption after a CBI coal scam investigator was arrested for taking bribe to settle a dispute. The CBI had arrested the chief investigator in the coal blocks allotment case for allegedly accepting a bribe of Rs.7 lakh to "settle" a land dispute for a businessman. Echoing similar sentiments BJP spokesperson Balbir Punj said that the Supreme Court should constitute an SIT to investigate the coalgate and the SIT should work directly under the supervision of the Supreme Court. The arrested persons are Superintendent of Police Vivek Dutt and Inspector Rajesh. They were arrested outside the CBI's headquarters. Meanwhile The CBI on Monday will move the Supreme Court to seek the removal of the officer who was arrested on Saturday.
