DMK MLA Anitha Radhakrishnan was arrested in Thoothukudi district on Friday, hours after the Madras High Court refused to grant him anticipatory bail in a case alleging defamatory and abusive remarks against Tamil Nadu Chief Minister Joseph Vijay.

The Tiruchendur MLA was taken into custody by the police and underwent a medical examination before being questioned by investigators. It was not immediately clear whether he would be remanded to judicial custody or released on bail by the local court.
