Patna, Dec. 12: The state vigilance bureau grilled former Bihar chief minister Rabri Devi?s brother and Gopalganj MP Anirudh Prasad, alias Sadhu Yadav, for three hours in connection with the flood-relief scam.

Yadav is accused of transferring Rs six lakh into his bank account from the account of the scam kingpin Santosh Jha.

The bureau discovered the alleged involvement of Yadav and issued a notice to him two weeks ago to appear before the department to be questioned on the matter today.

The three-hour-long interrogation at the vigilance office in Patna is said to have produced ?results? for the agency, which apparently intends to pursue the matter further and seek an arrest warrant against the accused.

Neither Yadav, nor the additional director general of vigilance, Neelmani, revealed details of today?s sessions.

?The interrogation is going well and according to the plan . We might appeal to the court to issue arrest warrant against the accused sooner or later,? said Neelmani.

Emerging from the office after three-hours of grilling, Yadav, too, put on a brave and sober face. ?I am not guilty. I don?t know what politics is being played. As for the session, I?ve answered all the queries of the agency. That?s all. The rest you can get from the agency itself,? said Yadav and walked away.

The main accused, Jha, along with the former Patna district magistrate, Gautam Goswamy, is lodged in Patna?s Beur Central Jail after he surrendered about three months ago.

The vigilance sources have allegedly discovered that Jha withdrew Rs six lakh from his bank account in January 2004, and the same amount was deposited in Yadav?s account on the same day.

The bureau also suspects the involvement of Niti Jha, a close associate of Santosh Jha and some others in the multi-crore flood-relief scam that was unfolded few months ago.
