The horrific incident happened during the late night hours of Thursday and the deceased was identified as Adityan, who was serving as the PMK's deputy secretary in Villupuram.
Police said Adityan had left his house on Thursday night and when he didn't return home, his family members lodged a complaint with the Vikravandi police.
Both the leaders have tested positive at a high time when Tamil Nadu has been witnessing a huge rise in daily Covid cases, triggering the possibilities of yet another wave.
After taking the baton of leadership in PMK, Anbumani has been on the drive to reaping a good scale of support for his new venture from across the state.
After his son was unanimously elected as the party's president, PMK founder Ramadoss had broken down in tears and visuals of the meeting have been going viral across social media.
He has been addressing the general body meeting of the district units across the state with the aim of reviving the party's base to win the next assembly polls in Tamil Nadu, due in 2026.
