K. Aadhimoolam, and wife A. Muthulakshmi of Mullipatti village near Pappireddipatti in the district, attempted to immolate themselves in front of the Collectorate here on Monday.

Both belonging to the Arunthathiar community said that they were taking the extreme step as the police were harassing them. Their son had married a caste-Hindu girl.

The police took them to custody and registered a case under section 309 (attempt to suicide) of Indian Penal Code. They have been remanded in judicial custody.

The couple came with a can of kerosene to the Collectorate to submit a petition at the weekly grievances redress meeting.
