Four people, including the principal of GA Inter College, where the exams for Vishun Rai (VR) College students was held, have been arrested in connection with the Bihar School Examination Board (BSEB) results controversy. 

Meanwhile, BSEB Chairman Lalkeshwar Prasad Singh resigned from his post after the Bihar government issued a show-cause notice against him on Wednesday morning, according to India Today.

Zee News reported that Singh was on Tuesday questioned by a Special Investigation Team (SIT) formed to probe the irregularities. A few computers and hard disks were also reportedly seized.

A senior SIT official was quoted by Zee News as saying: "Experts will examine the computers and hard disks to collect more information on the results of Class 12 Science and Arts examinations."

The Indian Express had reported on Tuesday that an FIR in this regard was filed on Monday night after Bihar Chief Minister Nitish Kumar ordered the police to form an SIT under the additional director general of police to probe the matter. The SIT has to submit a report to the state DGP within 10 days.

The Patna Police had on Tuesday registered the FIR against four students, the director of VR College, and the supervisors and teachers of the examination and evaluation centres in connection with the controversy.

A police official from Kotwali Police Station told International Business Times, India, the FIR had been lodged against Ruby Rai, Saurav Shrestha, Rahul Kumar and Shalini Rai.

According to the India Today report, answer scripts from all other schools in the Vaishali district of Bihar were sent to Kaimur and Ara for evaluation, but those from VR College were sent to Patna Boys' High School.

The SIT has also detained Viseshwar Yadav, the centre superintendent of Patna Boys' High school.

The BSEB has already cancelled the results of the toppers Saurav Shrestha and Rahul Kumar, who apparently did not score as per expectations in a retest conducted by experts on 13 toppers of the Arts and Science streams, India Today reported.

Ruby Rai, who had called Political Science "Prodigal Science," which according to her was a subject about cooking, has been given another chance and will have to face the experts on June 11.
