Maoists on Saturday killed a policeman, who was abducted last month, in Chhattisgarh's Sukma district and left his body near a village market, authorities said.
Police said they also recovered a handwritten note by the rebels which was left near the body of the policeman, Peela Das. Das was posted at Polampalli police station as auxiliary constable.
Local villagers alerted police about the body.
They said Das was returning to Polampalli, about 450 kilometres south of the state capital, on Monday to join duty when he was kidnapped by the rebels. He had served as a special police officer (SPO).
The Maoists in strife-torn Bastar zone are selectively targeting the former SPOs, who have been absorbed by the Chhattisgarh government into state police force as auxiliary constables since 2011 after passing a new law.
It was apparently done to do away with the strong objection raised by the Supreme Court which directed the state to disarm over 4,800 SPOs in Bastar zone who were working as adjunct policemen for anti-Maoist operations.
On July 14, the banned outfit killed four policemen, who had worked as SPOs, after they were abducted in Bijapur district. The Maoists left a letter near the bodies giving their reasons for killing them.
"All four, after joining as Chhattisgarh auxiliary constables, were harassing people, troubling young girls and women, burning houses, and had admitted to actively carrying out anti-Naxal campaigns. So they were given the death punishment," said their note.

The left-wing extremists had attacked Vijay Malik with sharp-edged weapons, the police said.
