Initially, the police had booked four accused -- Farman, Pawan, Sunder Singh and Sunny Uppal -- under section 302 (murder) of IPC after the postmortem report showed Tania died due to injuries on his head and face caused by a blunt object. The agency had also invoked charges under the SC/ST Act.
However, during filing of the charge sheet, CBI dropped the murder charges against the accused, saying Tania's killing was not pre-meditated but a result of an altercation over breaking of a glass counter of a shop in the market.
Recently, CBI and Tania's father Nido Pavitra's has also moved the court against the trial court's decision to drop charges under the SC/ST Act against the culprits.
