The bodies of four villagers abducted by Maoists a day ago were found in Bihar's Banka district on Saturday, police said.
On Friday, nearly 100 armed rebels stormed Pipradih village in Jamui district, about 200 km from in Patna, and attacked a family. They killed three members and abducted four of them.
"Police and central paramilitary forces have launched combing operations in the area and security has been heightened in the village," Jamui Superintendent of Police Ram Narayan Singh said.
Jamui is considered a Maoist stronghold.
Two weeks ago, Maoists had blasted a state-run school and abducted seven labourers engaged in the construction of a bridge in Jamui. They were later released.
