On October 3, a team of Indian Army personnel, engaged in the repair of a road in the Chumar sector in Ladakh, was questioned by a patrol party of China's People's Liberation Army. The Indian armymen, under strict instructions not to exacerbate tension on the border, demonstrated restraint. The face-off lasted about half-anhour, during which the PLA troops painted Chinese letters on the marking stones in red and destroyed a map made by the Indian troops.
