The case was registered yesterday under Section of 124 A (sedition) and 120B (criminal conspiracy) of IPC against unknown persons at Vasant Kunj (North) Police station following complaints by BJP MP Maheish Girri and ABVP.
"Kanhaiya Kumar has been arrested in connection with the case," a senior police official said.
Two policemen in plain clothes came to the JNU campus today and picked up Mr Kumar for questioning. He was later arrested, sources said.
A group of students on Tuesday held an event on the JNU campus and allegedly shouted slogans against the hanging of Parliament attack convict Afzal Guru in 2013.
The event occurred despite varsity administration having cancelled the permission following a complaint by ABVP members, who termed the activity as "anti-national".
The JNU administration has already instituted a "disciplinary" enquiry as to how the event took place despite withdrawal of permission and said it will wait for the probe report before taking any further action.
