COIMBATORE: Police arrested three more NTK cadres on Wednesday for staging a protest when Chief Minister C Joseph Vijay held a roadshow for his party candidate, P Sathyabama, during the Dharapuram by-polls.

This brought the total number of arrests in the case to 12. On Tuesday, NTK functionary M Karthika, who contested the Dharapuram by-polls unsuccessfully, was arrested along with eight others, including her husband.

Cops produced them before the court, where they were remanded to judicial custody and lodged at Coimbatore Central Prison. Meanwhile, Karthika and eight others have moved a bail petition in Dharapuram court.
