A G Ravi, Assistant Sub-Inspector in Muthupettai police station in the district, has been placed under 'wait list' (in service with no work assigned) for violation of code of conduct and service rules, police said.
He had erected the flex board in the town expressing his pleasure to work during the tenure of present Tamil Nadu Chief Minister.
The board which bore the official's name along with his picture, read: "Honourable Tamil Nadu Chief Minister Avargale.. I am delighted to work again during the golden age of your governance."
However, Ravi maintained that he did not owe allegiance to any party, but was personally a fan of Jayalalithaa.
"I had put up the board as per my wish," he said.
