Chennai, Dec 3 (IANS): A primary school headmistress in Erode district of Tamil Nadu was arrested on Saturday for allegedly making six Scheduled Caste students clean the school toilets.

Geetha Rani, the headmistress of Palakkarai Panchayat Union Primary School, was arrested from Perundurai in the district.

The issue had come to light recently when some of the students' parents noticed blisters on their wards' hands and enquired about it.
