The body has been kept at the mortuary of the Ratangarh (Churu) Hospital.
A large number of people gathered at Singh's hometown, Sanvrad in Didwana of Nagaur district, to console the family members and demanded a CBI inquiry into the encounter which took place at a village in Churu district.
"The family has not accepted the body so far. Their main demand is a CBI inquiry into the encounter," Nagaur Superintendent of Police Paris Anil Deshmukh told PTI.
Meanwhile, 25 people were taken into preventive custody tonight to control law and order in the area, he said.
Seventy-five people were arrested yesterday when they attacked a police party and injured the SHO of Jaswantgarh police station during a protest against the encounter.
Anandpal, who had managed to escape from custody of police while being taken back to high security prison in Ajmer from a court in Nagaur in September 2015, had taken a shelter in a house in Churu.
