In a pre-dawn attack, armed maoists virtually destroyed a police outpost and a government building besides injuring two persons in Orissa's Malkangiri district on Wednesday, police said.
Around 100 ultras attacked the police outpost and a nearby rest house at Padia, about 70 km from Malkangiri, nearly razing to the ground the two buildings using machinery they had forcibly taken from a road construction site, they said.
The sources said the maoists, who struck around 1 am, woke up the buldozer operator at the construction site and forced him at gunpoint to use the machine to bring down the buildings.
They also set ablaze the battery room of a BSNL tower and beat up the watchman and another person when they protested injuring them, the sources said.
The Malkangiri Superintendent of Police, Satyabrata Bhoi, confirmed the incident.
The ultras, who terrorised the local people, left after putting up posters asking people to boycott the ensuing elections and warned that those campaigning and taking part in the polls would be punished, the sources said.
Additional security force had been deployed in the area and combing operation launched to track down the attackers, police said.
