Students, including some girls, from Jawaharlal Nehru University (JNU) were staging protest outside the RSS headquarters on Saturday (Jan 30) against the death of Hyderabad University PhD scholar Rohith Vemula.
In the video, the Delhi Police personnel deployed on duty can be seen using force on the protesting students.
Delhi Chief Minister Arvind Kejriwal on Monday accused the BJP of using Delhi Police as a "private army" -- after a video showed policemen thrashing students protesting here two days ago.
Delhi Police "being used by BJP/RSS as their (private) army to terrorize and teach (a) lesson to anyone opposing the BJP/RSS," the Aam Aadmi Party (AAP) leader tweeted.
"I strongly condemn (the) attack on students" on January 30, he added.
The video, released by the AAP, showed policemen both in uniform and in civilian clothes charging at students from the Jawaharlal Nehru University and beating them with lathis.
Some officers were also caught on the camera fisting and thrashing student activists, and physically pushing them to the ground.
Delhi Police has not denied the authenticity of the video.
Referring to the earlier student protests at the Film and Television Insitute of India (FTII) and Hyderabad University, Kejriwal said: "FTII, Rohith case, Hyd Univ, IITs and now brutal attack on Delhi students.
"Modi government seems to be at war with students all across."
Delhi Police does not report to the Kejriwal government but to the central home ministry and Lt. Governor Najeeb Jung.
