His party, AAP, also attacked the Delhi Police accusing it of using "dictatorial" measures to "harass" JNU students and professors over the ongoing row in the varsity.
The party said the entire episode has brought the "anti-student" face of the BJP-led government.
"Modi ji wants to terrorise everyone by using police," Kejriwal said.
In a tweet, he said, "No anti-national activity shud be tolerated under any circumstances. Those who did it must be identified and punished" (sic).
AAP also alleged that BJP's student wing ABVP was involved in the "conspiracy".
The party demanded action against those who raised 'Pakistan Zindabad' and other 'anti-India' slogans, but claimed that the incident was being used to target students and professors.
"AAP condemns the way Delhi Police is using dictatorial measures to harass students and professors of the JNU. During the entire episode some facts have come to the light that ABVP is behind this conspiracy.
"It was FTII first and then it was Rohith Vemula and now it is JNU. This has brought anti-students face of this government. Modi ji should stop oppression of students," the party said.
A group of JNU students organised an event on the campus on Tuesday, on the anniversary of execution of Parliament attack convict Afzal Guru, and shouted slogans against his hanging, despite the varsity administration having cancelled the permission following a complaint by ABVP members, who termed the activity as "anti-national".
Following which, JNU students union president Kanhaiya Kumar was arrested yesterday on sedition charges.
