The head of the boy was found lying a few meters away from the body, the officer said, adding that identity of the victim is yet to be ascertained.
"During investigation of the spot, police found some material for carrying out a ritual, including incense sticks and earthen light lamps, besides a sharp-edged weapon, which indicates that some 'puja' was performed at the murder place," he said.
A case was registered and efforts are on to trace the culprits, he added.
