The 11 armed individuals, dressed in police attire and intercepted by personnel of the Army's 2 Mahar regiment in Imphal, were freed on Wednesday.
The men were detained during patrolling in the early hours of Tuesday, after they were found in possession of a significant arsenal, including AK rifles, INSAS rifles, SLRs, hand grenades, and bulletproof jackets.
