Expressing outrage over the incident, the students took out a procession in the campus and handed a memorandum to the district authorities, demanding tight security for students.
A number of students had also held a candle march last night to highlight the sense of insecurity among students after the incident.
The protesters had also handed over a memorandum addressed to the President of India demanding a CBI enquiry into the incident. They also demanded that the culprits should be arrested within the next 24 hours.
