Police said trouble erupted when the authorities of the place of worship at Devipattinam asked the processionists to pass the area without playing the instruments in view of the prayer time there.
Suddenly, some stones were pelted at the place of worship, prompting those inside there to retaliate leading to a clash in which scores of people suffered bruises and cut injuries.
Organisers of the procession said that a stone thrown by some miscreant led to the clash.
Tension prevailed in the area though the situation had been brought under control, police added.
