However, some students alleged that he took the step as he was humiliated by a faculty member.
"Moses Abhraham, a PhD student in the university's ACRHEM department, suddenly took out a blade and slit his wrist. He was immediately taken to the health centre on the varsity and later shifted to a private hospital. Now, he is safe...Doctors said there is nothing to worry about," Pro-Vice-Chancellor of UoH, Vipin Srivastava, told PTI.
On Friday evening, one of his teachers was teaching him and some others on research methodology on how to prepare their presentation for exams scheduled in two days.
He suddenly took out a blade and slit his wrist and took everyone by surprise, Srivastava said.
"I have been informed that the student has expressed apology for this act...maybe it was due to exam pressure or something else," he said, adding that the teacher is also shaken in view of his act.
He further said the student stays outside in an apartment with his friends.
Meanwhile, students alleged the faculty at the department allegedly did not allow Moses to attend seminars and had asked him to change his research area.
The suicide had triggered a huge political controversy.
