Naveen, who was with his group, met the rival group. However, as the argument escalated, the groups clashed, and Naveen's group hurled crude bombs at Mayajothi and his group and fled the scene. Vignesh suffered serious injuries in the attack. The Maduravoyal police rushed to the scene, arrested the five men, and launched a search for Naveen and six others who are absconding.
