District superintendent of police Kamalochan Kashyap told Bhasha/PTI that Kosa (30), an active member of Malangir area committee of the Maoists, was arrested by a team of CRPF and district police in Kirandul police station limits of the district.
Kosa was involved in Naxal activities for the past ten years, Kashyap said.
He was also a member of 'Dandakaranya Adiwasi Kisan Mazdoor Sangh' of Maoists, and president of its Tikanpal unit.
Kosa's responsibilities included recruitment, spreading the Naxal propaganda among locals and conducting reccee before attacks.
He was involved, among other violent incidents, in the February 28, 2014 attack in Shyamgiri, in which five security personnel including police station in-charge Vivek Shukla were killed.
