The Maoists pasted posters at Bangalwa, Jatkutia and Sakhaul villages under Dharhara police station announcing 'death sentence' to the mukhiya of Ladaiyatand panchayat Anil Yadav and three others, Deputy Superintendent of Police (DSP) Ranjan Kumar said.
All posters have been removed and seized, he said.
Similar posters were also found pasted on the walls of an empty government house at Masudan railway station, a nearby bridge and the walls of a rural bank building in neighbouring Lakhisarai district, he said adding those were also removed.
The four had played an active role in convincing about 25 Maoists to surrender before the authorities last month, he said.
A case has been lodged and an investigation is on, he added.
