One protestor has been injured in police firing at Malangawa-10 in the district on Monday. The identity of the injured is yet to be known. He has received a bullet in his chest. Preparation is underway to airlift him to Kathmandu for treatment. Police have fired three shots into the air and one round of fire at the protestors when they took to the streets protesting against the new constitution. The police resorted to firing after a huge mass of agitators started vandalizing the house of UML lawmaker Kamala Devi and tried to set fire to it, informed Chief District Officer (CDO) Meghnath Kafle. The protestors have dispersed now and police personnel have been stationed at the lawmaker's house. Madhesi people had staged a black-out at a time when the celebration was underway on the occasion of the promulgation of the new constitution. Irate Madhesi parties have been hitting the streets since weeks in protest of the new constitution.
