CBI sources said here on Sunday the chargesheet was filed earlier this week for anomalies found in 2007 in the appointment procedures. It also alleged that at least Rs 19 crore was siphoned off from government treasury in fake appointments from 2001 to 2006.

The case was handed over to CBI in 2009 following which the central probe agency grilled several police officials, including at least seven IPS officers.
