"Three platoons of Quick Response Teams were rushed to the town after the incident and the situation is under control," Prakasam district Superintendent of Police P Pramod Kumar said, adding efforts were underway to nab those involved in the clash.
The trouble started after YSR Congress workers waived the party flag when TDP workers were coming in a procession in the town. Workers from both the parties suddenly indulged in a verbal duel and tore apart flexi boards of respective parties, police said.
At least 10 persons from both the parties, including a constable, were injured during the clashes.
A large number of supporters from both the parties later held protests and counter protests and also blocked the Addanki-Narketpally road. Police intervened and dispersed the protesters.
