Tirunelveli: Faced with a series of agitations, police today arrested eight teachers for allegedly forcing Dalit students to clean toilets in a government-aided high school at a village in the district.

Backed by some political outfits, local Dalits have been staging a series of agitations in the past weeks demanding action against the teachers alleging that they were forcing the students of the school in Keelapathai Pandithankurichi near Kalakkad.
