Bhima Koregaon violence was pre-planned, claims Pune Police
Backstory: What really happened at Bhima Koregaon?
Every year on January 1, Dalits who follow BR Ambedkar, celebrate the win of their ancestors on upper caste Marathas in a war in 1818.
Dalits gather at Bhima Koregaon's Vijay Sthamb to celebrate this victory. This year marked the war's 200th anniversary and the celebrations were grand.
But soon clashes between Dalits and Marathas played spoilsport; one was killed and several injured.
Now, two teams of Police investigating different angles of case
Notably, the investigation has taken two routes: One which alleged Maoists were involved in the attacks, and other which thinks Hindutva groups are guilty.
While the Pune urban police are probing the supposed Maoist angle, the rural wing is handling the right-wing side.
Further, names of Hindutva leaders Milind Ekbote and Sambhaji Bhide 'Guruji' have also cropped up. Ekbote was arrested and released on bail earlier.
