With campaigning reaching high pitch ahead of the bypoll on February 13 in various wards in the constituency, a verbal spat erupted when BJP and AIADMK men crossed each other in the area.
Later they attacked each other with stones in which three BJP office bearers and five persons belonging to AIADMK were injured. Two vehicles, including a police one, were damaged.
Both groups blocked traffic demanding action against each other following which Assistant Commissioner Kabilan persuaded them to disperse.
