The roof of an under-construction building caved in when the Maoists exploded bombs at the police lines, killing two labourers, Superintendent of Police A V Homkar told reporters here.
While one died on the spot, another succumbed to his injuries on way to hospital, he said, adding that an unexploded IED weighing 30 kg was recovered and defused.
However, an executive engineer with the Central Public Works Department, Alok Srivastav, said that the damage to a couple of buildings was repairable.
The Maoists were scared of the construction of the Rs 30-crore police line spread over 72 acres on the outskirts as their movement would be restricted, a police official said.
