The former minister had passed away last year.
Sources said the Municipal Commissioner had refused permission for the statue, but DMK had moved the High Court and got the stay vacated.
The city Police Commissioner today sent a letter through Assistant Police Commissioner stating that the statue should not be unveiled as police had not received the court order.
The notice in this regard was pasted on the door of the party office here as the DMK secretary was away to receive their leader M K Stalin in Namakkal.
