"Two youths fired at another youth from a different community. It led to stone pelting and incidents of arson," a police officer said.
The officer added that for over two hours, people from the two communities hurled stones at each other at different places in the town.
"Some people blocked National Highway-8 and burnt tyres and two motorcycles. People from another group hurled stones at houses in a colony, smashing window panes," said the officer, adding that a dozen people were left injured in the clashes.
"We deployed heavy police force in the town today (Sunday). The administration also clamped section 144 of the Code of Criminal Procedure banning unlawful assembly of people. We have detained some people from both the communities," said the officer.
