The National Investigation Agency (NIA) has filed a fresh chargesheet against four additional individuals in connection with a case involving the propagation of the outlawed Naxal group`s violent agenda in Chhattisgarh, officials said.

Three of the chargesheeted accused -- Sunita Potam, Shankar Muchaki, and Dashrath alias Dasru Modiyam -- held positions in the Moolwasi Bachao Manch (MBM), a Maoist-affiliated front outfit that was outlawed by the Chhattisgarh government in October last year under the Special Public Security Act, 2005. The fourth individual, Mallesh Kunjam, was part of the Maoists` armed wing and remains on the run.
