Avinash, a self-proclaimed Maoist spokesman, had earlier sought to hold talks with the Chief Minister.
"We are keen to talk with the chief minister on the issue," he said.
The Maoists, who abducted four police personnel on Sunda, Aug 29 from Lakhisarai district, sought release of eight red rebels lodged in jail.
However, since the government failed to act, the Left Wing extremists extended deadlines several times but on running out of patience they killed one of the abducted policemen, identified as BMP havaldar Lucas Tete.
