The incident took place late Friday at the Kuzupathar village in Tinsukia district.
The slain policeman has been identified as Officer-in-Charge of Bordumsa Police station Bhaskar Kalita while the terrorist is yet to be named.
According to the police, the operation led by Kalita was based on a tip-off that a group of terrorists were hiding in the village.
As the security forces surrounded the village, the terrorists hurled a grenade and fired indisciminately.
Assam DGP Kuladhar Saikia is scheduled to arrive in Tinsukia on Saturday.
Saikia, who took charge as the state's DGP less than a week ago, will also visit the incident spot.
