Four videos have surfaced online of the incident, the latest being on Monday.
The team led by Deputy Commissioner of Police (Crime) Rajesh Deo visited the varsity''s library that was badly damaged during the alleged police action inside the campus last year, according to officials.
This is for the first time that a police team is visiting the campus for investigation after the violence, they said.
Members of the team analysed and videographed the extent of damage to the library. They also visited the proctor''s office, the officials said.
The case is being probed by the Crime Branch.
In a video that emerged on Sunday, paramilitary and police personnel can be seen thrashing students in the library. Two other videos, which appeared hours later, showed some youths with covered faces entering the library.
In the Monday video, police personnel can be seen raining batons on students who were trying to escape. Women students can be seen moving out while pleading with the police and one of the policemen is seen breaking a camera.
On December 15, police had used batons and teargas shells to disperse a violent mob during a protest against the Citizenship (Amendment) Act (CAA). They entered the university campus, saying that rioters had taken shelter there.
However, Jamia students had denied that they were involved in the violence and had alleged police brutality.
On Monday, a Delhi court directed the police to file a status report on whether it was investigating the officers who had allegedly barged into Jamia Millia Islamia and lathi-charged students.
The court has also sought an overall status report from the Delhi Police on the ongoing investigation in the case related to the violence near the varsity during the protest. PTI SLB AMP
