Guwahati: Director of Win Power Infra Private Limited Suresh Kumar Agarwalla, an accused in a bribery case registered by the CBI, surrendered at a special CBI court here on Monday.

Following his surrender, special CBI judge Mahmud Ahmed remanded him in judicial custody.

A source said the CBI later filed a petition, seeking him in custody for three days and the court will hear the CBI plea on Tuesday.

The source said Agarwalla had told the court that he was overseas and on his return, when he came to know about the case registered against him by the CBI, he surrendered before the court.

The CBI has registered the bribery case, which was related to alleged evasion of income tax, on April 12 under Sections 7, 11, 12, 13 (2) and 13 (1)(d) of the Prevention of Corruption Act, 1988, and Section 120B (criminal conspiracy) of the IPC.

The CBI has arrested commissioner of income tax (audit), Guwahati, Swetabh Suman, income tax officer (audit), Guwahati, Pratap Das, advocate and IT practitioner Ramesh Goenka, Goenka's son Amit and Pranjal Sarmah in this case.

Sarmah had allegedly handed over Rs 40 lakh to Ramesh for giving it to the two IT officials at the behest of Agarwalla. All the arrested accused are currently in judicial custody.

A statement, issued by the CBI, had said Suman and Das had allegedly sought illegal gratification to the tune of Rs 50 lakh through Goenka for showing undue favour to Agarwalla by passing a favourable order in an appeal arising out of assessment done in respect of a shell company owned by Agarwalla.

Ramesh is Agarwalla's tax consultant.

CBI sleuths had also conducted searches in the office and residential premises of the accused persons at different places in Guwahati, Jorhat, Nagaon, Shillong, Noida, New Delhi and other places and seized several incriminating documents and nearly Rs 49 lakh in cash.
