The boy, Prince, went missing last evening while playing outside his house.
Kanhaiya Lal, victim's father, who works at a factory, had lodged a missing complaint, a police officer said.
Police and family members had searched for the boy but failed. Locals this morning found the boy's body in a vacant plot near his residence.
A case of murder has been registered by police.
Lal told police that he did not have enmity with any one but suspected a youth who lived in his neighbourhood.
Police are suspecting it to be a case of sorcery.
