The tender was given to a Jaipur-based firm -- Kiran Infra Engineers limited -- which quoted a value of Rs 7,10,87,7901. Kishore Sharma, the Director of Kiran lnfra, then authorised Sorabh Dhanuka, a resident of Visakhapatnam, for the execution of tender work.

"Four officials of the East Coast Railway -- Subhas Chandra Das, Jalasutra Sumurtti, Sanjib Kumar Sahoo and Gopabandhu Bhoi -- obtained undue pecuniary advantage to the tune of Rs 13,32,0001 from B.K. Enterprise and Raj Kumar & Co through banking transactions in their names as well as in the names of their family members, without consideration from the concerned person (Sorabh Dhanuka), with whom they had official transaction," the CBI said.
