Hyderabad: A Right to Information (RTI) activist was killed in Telangana's Jangaon district in an apparent fallout regarding a land issue, police said on Monday.

Three people have been arrested for allegedly kidnapping and killing him, police said on Monday.

The killing of 70-year-old Nalla Ramakrishnaiah came to light on Sunday when his body was found in a water-filled quarry, three days after he went missing.

The victim's son had earlier filed a missing complaint.

G Anjaiah, the prime accused, had a dispute with Ramakrishnaiah over the latter complaining against him to government officials regarding a land issue, police said.

He allegedly hired a contract killing gang to eliminate Ramakrishnaiah, a police official said.

The gang allegedly kidnapped Ramakrishnaiah on June 15 at Pochannapeta. They "strangled" him to death using a towel and dumped the body in a quarry pond, police said.

Police apprehended Anjaiah and two contract killers on Sunday. They are trying to track others on the run.

Ramakrishnaiah had filed RTI applications, civil suits in the court and had also approached the Human Rights Commission against Anjaiah for cancellation of pattas (land deeds) pertaining to a government-assigned land in Pochannapet village which the latter had allegedly occupied.
