Sources said the insurgents identified as S Thoiba, Mutum Shanta and Yumkham Chaothoi were nabbed during a search operation at Andro area where PLA insurgents ambushed a party of police commandos yesterday.
It was not yet known whether the three, who were arrested yesterday afternoon, were involved in the ambush by exploding a improvised explosive device using a remote-controlled device while the commandos were approaching Andro area, sources said.
They said PLA flags and some mobile phones were recovered from the arrested persons who have been handed over to Imphal west district police station for further interrogation.
Meanwhile, official sources said said security and police personnel were put on alert at different places to prevent any untoward incident because today was the 34th Raising Day of the PLA.
