The case was filed before the designated court of NIA in Guwahati against N Dilip Singh, Senjam Dhiren Singh alias Raghu and Arnold Singh under various sections of Unlawful (Activities) Prevention Act, an official spokesperson said.
Dilip, self-styled chief of the 'foreign external affairs department' of banned terrorist organisation People's Liberation Army, was arrested by Delhi Police, Dhiren was nabbed by Kolkata Police and Arnold was picked up by NIA last month, he said.
The three were charged with imparting training to the cadres of banned CPI (Maoist) and supplying arms and ammunition to them.
The National Investigation Agency had on July 11, 2011 registered a case on the basis of reliable information that PLA, a banned terrorist group of Manipur, has formed alliance with the Communist Party of India (Maoist) for procuring arms, ammunition and communication devices for the latter for carrying out terrorist activities.
The investigation indicated that in and around June 2006, the PLA leadership met the top leaders of CPI (Maoist), which followed several other meetings between the two groups in 2006-2008.
