The six were Kamlesh Kumar Gautam, Raju Ranjan, Soni Rajak, Kumod Kumar, Rakesh Kumar Mishra and Anil.
Alam, who had arrived at the spot with Singh on being informed, fatally shot the three students in the head and dubbed them as dacoits in a report of the police station. Mukesh Ranjan, brother of slain student Vikash Ranjan was an informant of the fake encounter case.
The case was first probed by the local police, then CID and subsequently handed over to CBI. As many as 33 witnessed were examined by the court during the protracted trial. Alam, the prime accused, was denied bail by various courts ever since he was arrested in the case in 2003.
