Days after series of videos of the December 15 violence inside the Jamia Millia Islamia (JMI) emerged, the Crime Branch on Tuesday visited university campus for the investigation.

According to police, a team led by Rajesh Deo, the Deputy Commissioner of Police (DCP), Crime Branch visited the university's library that was badly damaged during the alleged police action inside the campus last year.

Police said that this is for the first time that a police team is visiting the campus for investigation after the violence. "Members of the team analysed and video graphed the extent of damage to the library. They also visited the proctor's office," said a senior police official.

Four videos have surfaced online of the incident, two went viral on Sunday while the other were seen doing round on social media on Monday.

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 CCTV 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. The incident is being probed by the Crime Branch.

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 JMI 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 university campus during the protest.
