Former chairman of the Bihar School Examination Board (BSEB) Lalkeshwar Prasad Singh, his wife - former JD(U) MLA Usha Sinha, and a relative - Prabhat Jaiswal - were sent to 14-day judicial custody in connection with the Bihar exam scam.
Special vigilance judge Raghvendra Kumar Singh accepted the plea of Special Investigation Team (SIT), which sought the custody of the three accused with an attempt to gather details about the merit muddle in the Class 12 examination this year.
Prabhat Jaiswal was arrested for having given them shelter for over a week when they went into hiding.
Four others - including deputy director of VR College Nand Kishore, principal of Ram Briksha Benipuri Mahila College Kumari Shakuntala, Nishu Singh and Rita Kumari - were also sent to judicial custody.
Bihar was rocked by the examination scam, which was unearthed after Ruby Rai, a student of Bishun Roy College in Vaishali district who had topped in the arts category, failed to answer basic questions and described political science as a "prodigal science that taught cooking".
The state government had ordered a SIT probe in the matter during which Bachcha Rai, the principal of Bishun Roy College, was arrested besides some other accused persons.
