First, Singh, who was DM of the district from 2012 to 2014 had renewed 13 mining leases in favour of the accused without calling for e-tender, between August and November of 2012. This renewal was for a period of three years. Then in 2015, the CBI alleged that Kumar unduly renewed these 13 leases of the accused again without calling for e-tender. Singh is an IAS officer of the UP cadre from the 1998-batch and Kumar is of the same cadre from the 2008-batch. They are the recent additions in the list of bureaucrats who have been booked by the central agency in connection with the snad mining corruption scandal in the state. Just a few months back the CBI had booked Abhay Singh and Vivek in connection with mining lease irregularities in Deoria and Fatehpur districts. This recent FIR has been converted from a preliminary enquiry the agency had registered on orders from the Supreme Court of India, after the Allahabad High Court had ordered the CBI to register six other PEs in connection with the case. In total, the CBI had registered seven PEs to look into irregularities in granting and renewal of sand mining leases in the districts of Deoria, Fatehpur, Kaushambi, Shamli, Hamirpur, Saharanpur and one other district. The CBI had named now-infamous IAS officer B Chandrakala in the Hamirpur case in January this year and also listed former Mining Minister in the Akhilesh Yadav government, Gayatri Prajapati as an accused in the Fatehpur case, adding that Mining Ministers during the period under probe will be coming under the scanner. Yadav himself was Mining Minister in the UP government for a short time when his government was in poer in the state.
