Former Bihar chief minister and Lalu Prasad Yadav's wife Rabri Devi, and their son Tejashwi were also among the 14 people named by the CBI in the chargesheet file in a court here.
The agency had recently questioned former Rabri Devi in connection with the case, they said.
The case pertains to allegations that Lalu Prasad, as railway minister, handed over the maintenance of two hotels run by the Indian Railway Catering and Tourism Corporation (IRCTC), a subsidiary of the Indian Railways, in Ranchi and Puri to Sujata Hotels, a company owned by Vinay and Vijay Kochhar, in return for a prime plot of three acres in Patna through a benami company.
As a quid pro quo, he "dishonestly and fraudulently" awarded the contract to them for the two hotels, the FIR had alleged.
After the tender was awarded to Sujata Hotels, the ownership of Delight Marketing Company also changed hands from Sarla Gupta to Rabri Devi and Tejashwi Yadav between 2010 and 2014. By this time, Lalu Prasad had resigned as railway minister.
