According to district Superintendent of Police Arabinda Kalita, two insurgents on a motorcycle coming from a forest area, under Charduar police station, fired at a police team when they were asked to stop and tried to flee.
In the retaliatory fire by police, one of the underground cadres was seriously injured and admitted to Tezpur Kanaklata civil hospital where he later succumbed to his wounds and the other cadre escaped, Kalita said.
Two grenades, one pistol, four live ammunition and a bike were recovered from the slain militant, he said.
Today's encounter is the second since yesterday in the district when another cadre of the Songbijit faction killed at Damanpur near the Assam-Arunachal Pradesh border.
Police recovered a pistol, two magazines and seven rounds of live ammunition.
