The Delhi Police has served a notice to JNU asking 30 of its students to join the probe in a sedition case over an event where anti-national slogans were allegedly raised last year.

The notice that is addressed to the JNU vice-chancellor contains names of students affiliated to the Left student groups which dominate the campus politics.

Some of the students, whose names figure in the notice, including AISA (All India Students' Association) leader Shehla Rashid, and Aprojitha Raja, the daughter of CPI national secretary D Raja, were active in a movement demanding release of the three students who were arrested in the case.
