However, the university authorities remain unconcerned by this situation, new students allege.
Ragging takes place from dawn to night, mostly at Sinharaja 6 hostel at the university premises.
The new students are denied their breakfast, causing around five to six students to obtain treatment at the university clinic or at Pambahinna Hospital, lecturers say.
Lecturers of the sociology faculty are boycotting convocations and other student activities in protest.
Vice chancellor denies
When contacted, vice chancellor Prof. Sunil Shantha denied ragging has reached serious proportions.
According to him, the fresh students cannot stand even a small incident and their parents get easily disturbed.
He said an investigation was underway into an attempt by seniors to take two female students out of their hostel by force on a holiday.
