The police said that one of the militants, arrested by the Assam police earlier, was Doino Ram Reang, self-styled president of the United Democratic Liberation of Barak Valley.
The trio was wanted by the Mizoram police for a murder case at Thinglian village and the abduction of three executives of the Assam-based road construction company - Anupam Bricks and Concrete Industries Limited (ABCIL) on June six, 2011.
A team of the Mizoram Police commando rescued the three captives after a shoot-out with the abductors a few weeks later.
Doino Reang denied that his organisation was involved in the abduction while some senior police officials also suspected that the kidnapping was done by United Democratic Liberation Army (UDLA) a breakaway faction of the UDLFB.
