The body of an Indian journalist who had reported on alleged corruption in the country has been found in a septic tank in Chhattisgarh state.

Mukesh Chandrakar, 32, went missing on New Year’s Day and his family registered a complaint with the police.

His body was found on Friday in the compound of a road construction contractor in the Bijapur town area after officers tracked his mobile phone.

Three people have been arrested in connection with his death, reportedly including two of his relatives. A media watchdog has demanded a thorough investigation.

Police in the Bijapur district did not find anything during an initial visit to the compound on 2 January.

“However, after further inspection on 3 January, we discovered Mukesh’s body in the newly floored septic tank near the badminton court,” a senior police officer said, referring to the fact concrete slabs had been placed on top of the tank.

Police said his body showed severe injuries consistent with a blunt-force attack.

Mr Chandrakar, a freelance journalist, had reported widely on alleged corruption in public construction projects.

He also ran a popular YouTube channel, Bastar Junction.
