Amit, who underwent a lie detection test by the CBI, has been charged with being the mastermind behind the murder, which sparked a political storm in Chhattisgarh ahead of the assembly polls in 2003.

Of the accused, Amit and Chiman Singh are in judicial custody while three police officers, including station house officer of Raipur Kotwali, Viswakumar Pandey, were arrested in connection with the case on Thursday night. Pandey was produced in the court on Friday, and was sent to judicial custody till July 29.

The CBI chargesheet has been divided into three parts, with the first one dealing with those who hatched the criminal conspiracy and killed Jaggi.

The second part deals with all those, including three police officials, who wanted to destroy the evidence and foist a false case to save Amit and the others.

The last part in the chargesheet talks about those who sought to own responsibility for Jaggi's killing in return for monetary consideration.
