Raipur: Maoists went on a rampage in parts of Chhattisgarh's insurgency-hit Bastar region killing two people, including a security personnel, and damaging a part of a railway line, leading to the derailment of two engines of a goods train.

A Special Task Force member and a police informer were killed in separate Maoist incidents in Sukma district, Sukma Deputy Superintendent of Police Irfan-Ul-Rahim told PTI.

A joint contingent of the STF and the district police force was carrying out an anti-Maoist operation in the densely forested borders of Dantewada and Sukma districts, which are located around 400 km away from Chhattisgarh state capital Raipur.

After they reached Dudhiras forest under Gadiras police station limits, a group of armed Maoist cadres opened indiscriminate fire on them killing constable Gautam Rajwade, the DSP said.

However, the Maoists escaped into the core forests after the contingent retaliated heavily, he said.

In another incident, a 32-year-old police informer, Boodu Ramesh, was shot dead by armed Maoist rebels in Konta town under Konta police station limits.

Ramesh was attacked while he was returning to the Gaganpalli rehabilitation camp, the DSP said, adding that combing operations are on in the region to nab the attackers.

Also, two engines of a freight train?were derailed in Dantewada district after alleged Maoist removed fishplates from railway tracks on the Kirandul-Vishakhapattanam route injuring a loco pilot and his assistant.
