AIADMK MP from Mayiladuthurai, O S Maniam was assaulted at Vedarayam by a group of men. The party cadres staged a protest on Friday in Mayiladuthurai demanding the arrest of the group. The MLA who was admitted in Nagipattinam hospital for treatment was assaulted by a group which is expected to be due to inner party feud. The inner party sources said that the party former secretary Pazhaniappan and his supporters have planned the attack due to the conflicts that arose as a result of shuffling of the office bearers within the party. An FIR has been filed in this regard at the Vaimedu Police Station against 36 people.
