I told him it was serious during those days. I said the most common ragging was smile wipe where we were told to smile and then wipe it off by moving our fingers over lips. I asked Ashutosh to do the same but he refused and I said ok. Nothing else happened,' said Hani.

Akshay Chaudhary said he did not even talk to Ashutosh and was just present there as he shares the room with Hani.

'After Ashutosh left, Hani received a threatening call from his elder brother. In the evening, the hostel warden called us and without hearing us reported the matter to the college management,' Akshay said.

The two said they were not told about the disciplinary committee meeting.

'We want to meet the principal and explain everything. Nobody told us we have to be present in the meeting. The decision has been taken without taking our view,' said Akshay.

Many students criticised the college's decision and raised slogans within the campus.

'There is no clear-cut definition of ragging. Asking juniors their name and other details is just a way to make them open up,' said Rakhi Gupta, a second-year student.

'Expelling two students will not act as a deterrent and ragging will continue. Authorities need to think of what can be done by taking students along to curb the menace,' said another student.

Deputy Commissioner of Police (North) Sagar Preet Hooda said the police are yet to receive a formal complaint from the college.

'The college has informed us about the incident but we are yet to receive a complaint,' Hooda told IANS.

Delhi University's current academic session started July 16 with tough anti-ragging measures being implemented with the help of Delhi Police.

During the past year, the country witnessed 88 cases of ragging, of them 12 proved fatal.
