The case relates to alleged inflammatory speeches delivered at the Elgar Parishad conclave, held at Shaniwarwada in Pune on 31 December 2017, which the police claimed, triggered violence near the Koregaon-Bhima war memorial in the district the following day.
Pune Police has claimed the conclave was backed by Maoists.
During the probe, the police arrested Left-leaning activists Sudhir Dhawale, Rona Wilson, Surendra Gadling, Mahesh Raut, Shoma Sen, Arun Ferreira, Vernon Gonsalves, Sudha Bharadwaj and Varavara Rao for alleged Maoist links.
These nine activists, currently in jail, are among 11 people booked by the NIA in the Bhima-Koregaon case.
