The Central Bureau of Intelligence has filed charges against former Jharkhand chief minister Madhu Koda, his aide Vijay Joshi, former coal secretary HC Gupta, ex-chief secretary A K Basu and four others, in connection with the allocation of coal blocks to Kolkata based Vini Iron Steel and Udyog Ltd. In the case of Vini Iron Steel, against which the agency had registered an FIR in 2012 among the first set of coal scam cases, the CBI found that the state government gave a 'positive recommendation' to the company only when its owners sold it to Koda confidante Vijay Joshi. Besides Koda and ex-bureaucrats, the agency named two serving public servants Basant Kumar Bhatttacharya and Bipin Bihari Singh, and director of Vini, Vaibhav Tulsyan. All accused have been charged for the offences punishable under sections of the IPC and provisions of the Prevention of Corruption Act. The charge sheet was filed before special CBI judge Bharat Parashar, who scheduled it for consideration on December 22. The CBI also filed two separate chargesheets in coal scam cases involving Nagpur based Grace Industries Ltd and Jharkhand based Jharkhand Ispat Pvt Ltd.
