The body of Bharti Balmiki, with bullet wound, was found in fields this morning, said Vijay Singh, Dankaur SHO.
Agitated over the death, villagers put the body on road and blocked traffic for hours, police said, adding that they were demanding arrest of the accused.
The blockade was lifted after senior police officials reached the spot and assured the agitating villagers of action.
Balmiki, a resident of Bilaspur, went missing last evening and his body was found today, police said.
According to sources, Balmiki's sister was allegedly kidnapped last year by one of the three accused.
Balmiki had filed a complaint against him, police said.
