Three policemen, including an officer, were killed when armed Naxalites attacked the Bishrampur Police station in Bastar district of Chattisgarh.
"Over 50 armed Naxalites came in four vehicles to Bishrampur Police station last night and opened indiscriminate firing and then triggered multiple landmine blasts," Bastar Range Inspector General of Police, Rajinder Kumar Vij, told PTI over phone.
An Assistance Sub-Inspector and two Head Constables were killed on the spot while another constable was seriously injured in the attack, he said.
The extremists later set off three land mines and blew up the police station, the IGP said.
The police station was having 15 security personnel, but no weapons and ammunitions were issued to it fearing that the Maoists could loot that, police sources said.
After the incident, the Naxals went to Dhamtari district from where they could have slipped into Nabrangpur district of neighbouring Orissa, the sources said.
When the attack took place, Chattisgarh Director General of Police, Vishwaranjan, was present in Bastar district which is infested with naxal menace for the last two decades.
