The two were shot dead near a school in Ranchi district's Bundu area last evening.
"One of them was a SPO," Ranchi Senior Superintendent of Police Prabhat Kumar said.
"SPOs are appointed to gather Maoist-related information on a monthly remuneration of Rs 3,000," a senior police officer said.
Stating that there was no qualification for SPOs and the job was not permanent in nature, he said reviews were done every three months to assess their performance.
