Kovan was arrested on October 30 for alleged sedition, uploading "defamatory" electronic content against Chief Minister J Jayalalithaa and "disturbing" public peace. He was granted bail by the high court later.
The singer of Leftist arts and literary outfit 'Makkal Kalai Ilakkiya Kazhagam' submitted that he was engaged in building up a movement among the people on various issues faced by them and has sung a number of songs and done a number of roadshows.
The case was registered after seeing the song on a website. There was no material evidence and still police arrested him, Kovan alleged.
The arrest was made in violation of the Constitution, human rights and other laws, he contended and sought quashing of the FIR.
