The Central Bureau of Investigation on Tuesday issued fresh summons to Rashtriya Janata Dal chief Lalu Prasad Yadav and his son Tejashwi Yadav on October 5 and 6, respectively, for questioning in connection with an alleged corruption case, ANI reported.

Yadav is accused of illegally giving a tender to a private hotel firm when he was the railway minister in 2006.

This is the investigating agency’s fourth summons to the Yadavs in this case. The fresh summons were issued after the two expressed their inability to go to the Central Bureau of Investigation’s headquarters.

On July 7, the agency had raided more than 12 locations, including the homes of Yadav, his wife Rabri Devi and Tejashwi Yadav, in Delhi, Gurugram, Patna, Ranchi and Puri.

The CBI had alleged irregularities in the tenders allotted to private company Sujata Hotels in 2006 to develop and maintain the railways’ heritage BNR Hotels in Ranchi and Puri. The agency claimed that, in exchange, Yadav had received a two-acre plot in Patna, where a mall is being built.
