Students under the banner of Left-affiliated All India Students Association (AISA) and Students Federation of India (SFI) and Congress-affiliated National Students Union of India (NSUI) marched to Shastri Bhawan to seek HRD minister Smriti Irani's intervention in the issue.
The protest turned violent as students tried to jump over barricades and attacked security personnel causing injuries prompting the police to use water cannons and detain students.
According to police officials, around 115 students have been detained so far. The Additional DCP had to get his leg plastered after the incident, the officials said.
The dead student, Rohit Vemula, was among the five research scholars who were suspended by Hyderabad Central University (HCU) in August last year and also one of the accused in the case of assault on a student leader. They were also kept out of the hostel. The suspension was revoked later.
The issue also took a political turn with allegations that the extreme action was a result of discrimination against Dalit students at the behest of Dattatreya, who had written a letter to Irani, seeking action against their "anti-national acts".
The HRD ministry has constituted a two member fact finding team to look into the the incident.
