The CBI's probe into the CGPSC 2021 recruitment alleges systematic manipulation: a coaching operator with prior access to question papers ran targeted preparation sessions at a Mahasamund hotel days before the mains, helping relatives of senior officials and business families secure top ranks. The agency's final charge sheet of about 400 pages, filed in January 2026, names 29 accused including a former commission chairman; 12 were in jail and one absconding at filing.
