On the complaint of the victim's family, an FIR was lodged against the accused, who is the son of the victim's uncle, and efforts are on to nab him.
The decision has been taken in compliance with the Supreme Court order in Tehseen Poonawala vs Union of India case, Singh said.
The deceased had been identified as Bachcha Singh (50) and Kapoor Singh, alias Kallu (46), residents of Raha and Jalala villages, respectively, said SHO RB Singh.

According to reports, the girl, a resident of Ata area in Jalaun district, went out for some work on Saturday evening, but never returned home.
The statement from the Uttar Pradesh police came hours after a man was allegedly killed and another got critically injured after they were beaten up by a mob on suspicion of child-lifting in Sambhal.
In the latest incident in Sambhal, a man suspected of being a child lifter was thrashed to death by a mob on Tuesday.
An FIR was registered in Etah on Monday in connection with the incident based on a complaint filed by Beena Devi.
