Dinakaran and his loyalists P Vetrivel, one of the 18 AIADMK MLAs recently disqualified from the Tamil Nadu assembly under the anti-defection law, and V Pugazhenthi have also been named as accused in the case, the police said.
This is the second case slapped against Dinakaran, who is engaged in a tussle for power with Palaniswami, by the state police.
Earlier, the sidelined AIADMK leader, along with Tamil actor and party functionary Senthil, had been booked for allegedly making defamatory remarks against P Kumar, the party MP from Tiruchirappalli.
The Madurai Bench of the Madras high court had restrained the Tiruchirappalli police from arresting them.
Responding to the latest case against him, Dinakaran alleged that it was filed since his rival Palaniswami “is the police minister”.
The chief minister also holds the Home portfolio, under which comes the police department.
“This government is anyway going to fall. They are doing such these things since he (Palaniswami) is the police minister... Let them do what they want. The AIADMK supporters and the people are going to send them home,” Dinakaran told reporters in Chennai.
