What are/were some of the instances of ragging at MNNIT, Allahabad?

One of my relatives was a student of MNNIT Allahabad and had experienced and eye-witnessed ragging in the university. According to him, the culture of ragging was restrained at MNNIT Allahabad after 2002. 

• The common place to rag and trouble freshers was the hostel area, which was outside the campus. All the freshers were asked to walk in queues. For boys, the dress code was a white shirt with a red third button, white pants, black shoes. For girls, it was white salwar and kameez, black shoes, oiled hair with the compulsion of ribbon. They were supposed to wear this uniform for two-three months. Furthermore, the seniors had asked the freshers to always look at their third button (the red one) whenever they were nearby them. 
• Room visits by seniors used to be a norm. While few seniors used to ask only questions and share their practical experience with juniors, many also used to ask the juniors to salute them at a 90-degree angle, or Paper dance, etc. Some seniors also used to make juniors do their practicals/assignments. 
• There used to be a railway track inside the campus and juniors were often asked to run on the track late at night, in earlier days. 

The situation started to change after 2000/2001 when a student allegedly died from his injuries due to ragging. The University administration started taking complaints seriously and worked their best to maintain peace at the university.
