New Delhi: The CBI has written to the Madhya Pradesh government seeking action against 229 students who took admission to four private medical colleges in Madhya Pradesh allegedly through the Vyapam scam.

The students had allegedly not appeared in any entrance exam and got in through the management quota by paying hefty amounts in 2012.

The Vyapam professional exam and job recruitment scam had come to light in 2013 and the CBI filed its second chargesheet on Thursday against 592 people.

The CBI chargesheet, filed in a Bhopal court, named the chairpersons of the four medical colleges - J.N. Choksey of LN Medical College, S.N. Vijaywargiya of People's Medical College, Ajay Goenka of Chirayu Medical College and Suresh Singh Bhadoriya of Index Medical College - for involvement in the scam, sources said.

While three chairpersons refused comment, Bhadoriya claimed neither his name nor that of the college was mentioned in the CBI chargesheet.

A total of 229 admissions were made by these four colleges under the management quota by charging amounts between Rs 50 lakh and Rs 1 crore per seat, CBI sources said.

These students did not take any entrance test, according to the sources.

The CBI sources said Index Medical College took in 88 such students, Chirayu Medical College 54, People's Medical College 46 and LN Medical College 41.

These admissions were done allegedly by Vyapam officials in connivance with a section of officials of the Madhya Pradesh medical education department and middlemen.

Impersonators - "bright" students who had taken coaching for the entrance test, had allegedly been hired to appear for the medical exams in place of the original candidates.

Later, Vyapam officials replaced the photographs of the impersonators with those of the original candidates on the admit cards, according to the CBI chargesheet.

The Opposition Congress said it would "take the state government to task" over the Vyapam scam in the winter session of the Assembly beginning on Monday. PTI
