Chennai/New Delhi: Protests continued today over de-recognition of a students' body, comprising mostly dalits, by IIT-M as NDA ally RPI joined the chorus against the premier institute's action, terming it as an "act of injustice" and "attack" on freedom of expression.

Protests were held in Chennai and the national capital against the institute's decision to temporary de-recognise Ambedkar-Periar Study Circle (APSC) by the IIT-Madras management after an anonymous complaint that it was spreading "hatred" against Prime Minister Narendra Modi was forwarded to it by the Union HRD ministry.
