The encounter started around 11 am when Maoists opened fire at security forces in Irpanar village in Narayanpur district, which forces say, is a hotbed of Maoists in Chattisgarh.
The injured security men have been taken to Raipur for treatment while bodies of those killed including two sub-Inspectors and two District Reserve Guard constables have been sent to Narayanpur district headquarters.
"This is the first encounter between Maoists and security forces in the area which is a stronghold of Maoists and there are possibilities that they have suffered heavy losses as well" said Mr DM Awasthi, Special Director General anti-Naxal Operations.
Earlier on January 6, in another encounter a Maoist was killed in Chhattisgarh's Bijapur district. Additional Superintendent of Police Mohit Garg told news agency PTI that a team of District Reserve Guard was carrying out counter-insurgency operations in the interiors of Gangaloor when they came under heavy firing from Maoist guerillas.
