Acting on a tip off that some Maoists had gathered near Tiletand locality to collect Rs two crore from a construction company last night, four companies of CRPF's COBRA battalion rushed there and in the ensuing encounter which continued throughout the night a woman Maoist was killed and another injured, CRPF IG (Bihar-Jharkhand) Arun Kumar said.
The gunbattle between the security forces and the Maoists was still on, he said.
A walkie talkie, an Insas rifle and a haul of ammunition were recovered from the spot, Kumar said.
The arrested Maoists had attacked a Special Auxiliary Police (SAP) establishment in Goh (Gaya) in 2013 in which they killed three SAP personnel and looted 30 arms, Kumar said.
