Violence in Manipur first broke out last month after thousands of people participated in a protest march to oppose the demand of the Meiteis to be included in the Scheduled Tribes category.

The protestors included the Kukis, one of the larger tribal communities in Manipur. For months now, they have been at loggerheads with the state government, and, in particular with Chief Minister N Biren Singh, who the community claims harbours Meitei “majoritarian” sentiments.

On Sunday, the Centre appointed a three-member committee headed by former Chief Justice of the Gauhati High Court Ajai Lamba to investigate the violence. Besides Lamba, the committee comprises retired Indian Administrative Services officer Himanshu Shekhar Das, and retired Indian Police Service officer Aloka Prabhakar.

Manipur BJP calls for removal of Assam Rifles

The Manipur unit of the Bharatiya Janata Party on Monday urged Prime Minister Narendra Modi to remove all troops of the Assam Rifles paramilitary force deployed in the state.

In the letter, state vice-president Ch Chidananda said that while the Assam Rifles have “apparently not [been] performing their duty sincerely as expected.”

On Friday, a standoff was reported between the Assam Rifles and the Manipur Police in Sugnu, according to The Times of India. Troops of the Assam Rifles had surrounded the Sugnu police station and blocked its entrance by parking two bullet-proof vehicles without informing the police. Both sides were on the verge of physical confrontation to the extent of pointing guns at each other, the newspaper reported.

“As a result of their [Assam Rifles], people have lost faith in them and protesting against their unethical actions,” Singh said in his letter to the prime minister. “All highways are blocked to stop them. It is a matter of concern that people might lose trust in other Central forces also because of the action of the Assam Rifles.”
