Maoists blew up four houses by dynamites on suspicion of their owners being police informers in Bihar's Nawada district, police said on Wednesday.
An armed squad of nearly 200 Maoists descended on Jamunia village and destroyed four houses of their 'renegade comrades' late last night, Superintendent of Police Vinod Kumar said.
All the occupants were ordered out before the ultras blew up the houses using dynamites.
The SP said three Maoists had been arrested last Saturday from Nawadih village under Rajauli police station before attacking Dilha railway station.
The rebels, he said, suspected that their former comrades had informed the police about their presence at Nawadih that resulted in police action.
Kumar denied reports that some villagers were kidnapped during the Maoist operation.
