DMK advocates submitted a petition with the City Police Commissioner S George seeking action against AIADMK men for sticking posters around the city defaming DMK chief M Karunanidhi, here on Tuesday. Advocates, led by party legal secretary R S Bharathi, told the media that they have insisted action under the legal framework. The posters flayed the DMK stir led by Karunanidhi as a ‘stupid one’ besides addressing Karunanidhi as a ‘brainless man’ and adviced the public not to fall prey to the main person responsible for the acute power shortage - MK.
