The Manipur Police is yet to make any arrests in connection with the shooting.
Formed in 2015, after two factions developed within the small Aimol ethnic group, the new outfit in the press release said it was forced to form the outfit to protect the small Aimol community of less than 10,000 people.
The ethnic group had been facing continuous threats and intimidation from suspected NSCN(IM) militants, which wanted the tribe to be called Aimol Nagas, the police said.
