Hyderabad PhD scholar Rohith Vemula committed suicide because he was frustrated over personal reasons, says a judicial commission after investigating the death that led to massive campus protests by students last year. The 26-year-old hanged himself on 18 January last year, days after he and four other students were suspended by the Hyderabad Central University and barred from its hostel. His friends and family alleged that he was ostracized because he was a Dalit.
