Hyderabad, Jan 21 (ANI): Four days after Dalit PhD scholar Rohith Vemula ended his life, the Akhil Bharatiya Vidyarthi Parishad (ABVP) student leader Nandanam Susheel Kumar, with whom Vemula had a tiff, alleged that Ambedkar Students Association (ASA) members attacked him in the presence of university security personnel and forced him to apologise. He said the reason of Rohith’s death should be examined and there should be a fair enquiry in it.
