Maoists went on rampage in Telangana's Bhadradri Kothagudem district early Saturday, killing one and injuring another former guerrilla member, whom they suspected of being police informers.
The Maoists also set ablaze several vehicles in three separate incidents in the district bordering Chhattisgarh.
The extremists of Communist Party of India (Maoist) struck after midnight.
They shot dead P. Jogaiah, who died on the spot in the attack in Veerapuram village.
Maoists also opened fire on another person at Suryanagar in Bhadrachalam town in the same district. M. Ramesh escaped with bullet injuries on his hand.
Both Jogaiah and Ramesh were former Maoists. Police said they were attacked as Maoists suspected them to be acting as informers for police.
The Maoists also burnt down four trucks, two JCBs and a tractor at Bhupatiraopet in the same district.
They abducted two workers from one of the trucks but later released them.
The attackers left behind a letter saying their action was in protest against the illegal sand mining in the area.
About 40 to 50 Maoists, who had reportedly crossed over from Chhattisgarh, carried out the attacks after forming three teams.
Following the attacks, police sounded an alert in the area and launched combing operations.
Telangana was once the stronghold of Maoists but their activities have been brought under control by sustained police operations.
Police claimed that in 2017, Maoist violence declined by 90 per cent.
Director General of Police M. Mahender Reddy said in December 2017, that the police were maintaining the vigil, especially in areas bordering Chhattisgarh to foil any attempt by Maoists to regroup.
