The Police had used tear gas to quell a tense situation in the Kataraganma area, a short while ago.
The Police have also arrested 63 people, including 15 women, for protesting in an unruly manner.

"One police officer has already been arrested. We urge the public to remain calm and maintain peace. Police have been instructed to work with the villagers to quell the situation," the Minister said, in a statement on Twitter.
