Violence sparked off after a man parked his bike outside a house despite objections from some youths belonging to the minority community, last evening.
People from both communities pelted stones and empty liquor bottles stored in a factory. The unruly mob vandalised some houses and also misbehaved with the occupants.
They targeted the police, leaving 20 police personnel, including the officiating Police Commissioner Biju George and ACP Rajesh Meel, injured. Meel had to be hospitalised.
"The situation was brought under control by deploying additional force," Additional Commissioner Girraj Meena said adding, ten persons involved in the violence have been arrested.
