The inquiry committee set up by Indian Institute of Technology Bombay after the death of its student Darshan Solanki last month allegedly by suicide has ruled out caste-based discrimination and hinted at deteriorating academic performance as a possible cause.

Originally from Ahmedabad in Gujarat, 18-year-old Solanki, a first-year student of B.Tech (Chemical) course, died on February 12 after allegedly jumping off the seventh floor of his hostel on the campus in Powai.
