Acting on specific information, a joint team of police and CRPF personnel launched an operation in Khardang area of the district and the militant was killed in the encounter that ensued, police said.
The security forces recovered a US-made carbine, 10 rounds of live ammunitions, a magazine, six writing pads and several extortion demand letters from the slain militant who was also identified as a member of the ULFA anti-talk faction.
The militant was suspected to have been the mastermind behind an IED blast when a convoy of CRPF vehicles was crossing Khardang area on August nine. But none was injured in the attack.
The anti-talk ULFA faction headed by Paresh Barua has, however, denied the militant was one of its members.
