While the police have initially claimed that the boy died after eating spoiled food, the further probe revealed that he was beaten by the cops to death.
The event has come weeks after the state ruling MK Stalin's regime has come under fire for the back-to-back custodial deaths that happened in the state.
His family had alleged that the police officers of Keezhathooval station were responsible for Manikandan's death as he was beaten and tortured by them.
