The Maoists swooped on the village last night, picked up six-seven people from an ongoing cultural programme and took them away to a nearby spot where they fired at them indiscriminately, sub-divisional police officer Rajesh Kumar said.
While three persons were killed as many were injured, the SDPO said.
Among the dead was one Sanjay Yadav, who had recently deserted the Maoist rank.
The Maoists also burnt Yadav's vehicle and took away his arms including a rifle, a pistol and around 100 cartridges, the SDPO said.
The three injured have been admitted to Anugrah Narain Magadh Medical College and Hospital (ANMCH), the SDPO said.
