People living in areas adjacent to the mountainous areas have complained about the arrival of Kuki militants in the valley and firing on civilians. At least three people were injured in a similar incident recently in Moidangpok village of Imphal West district. The period of curfew relaxation in the state has been reduced by two hours, due to which the restriction is now in force from 5 am to 2 pm. Chief Minister N. Biren Singh appealed to the people last evening not to set fire to the houses of innocent people. He told that three people including a former MLA have been arrested in the New Chekon incident. The mob had thrashed the man with the weapon, while three others fled the scene. There was no casualty in the incidents of setting houses on fire. ,
