Ranchi, Jul 6 (IANS): The Central Bureau of Investigation (CBI) has filed five cases of irregularities in appointments of state administrative officials, lecturers and doctors, an official said Friday.

"Total five cases have been lodged in different examinations conducted by the Jharkhand Public Service Commission (JPSC). The FIR has been lodged against former JPSC chairman Dileep Prasad, its members, and 19 administrative officials selected through second JPSC examination in 2006-2007," a CBI source told IANS.

The Jharkhand High Court, hearing a public interest litigation (PIL) in June, had ordered a CBI probe in all the examinations conducted by the JPSC since its formation.

Till now the JPSC has conducted three examinations of administrative officers, one for lecturers and one for doctors among others.

After the second JPSC exam results, the unsuccessful candidates had made hue and cry alleging irregularities in appointment of the administrative officials.

The state government handed over the probe to the state vigilance department in 2009, based on which 39 officials were dismissed in 2010.

Dileep Prasad and JPSC member Shanti Devi are in jail in connection with the irregularities in these JPSC examinations.
