Market regulator Sebi is seeking the Supreme Court's permission to interrogate Satyam's [Get Quote] disgraced founder Ramalinga Raju and his brother Rama Raju in connection with the Rs 7,800-crore (Rs 78 billion) fraud in the IT company.

Solicitor General G E Vahanvati submitted the request before a bench headed by Chief Justice K G Balakrishnan on behalf of Sebi.

The bench has posted the matter for mentioning tomorrow.

Last week, the Andhra Pradesh High Court had posted Sebi's identical plea for hearing on February 9 without giving an ex-parte order allowing the regulator to quiz the Raju brothers.

Sebi had moved the high court challenging a lower court order, which denied it permission to interrogate the Raju brothers, who are in judicial custody.

A probe team from Sebi had landed in Hyderabad on January 8, a day after Ramalinga Raju disclosed the massive accounting fraud in the IT company.
