Police sources said that the three students, Abdul Bari, Junaid Ashraf and Rahim Yusuf were spotted during the riots and at the protest attended by Sharjeel Imam.
The Delhi Police interrogation of Shaheen Bagh mastermind Sharjeel Imam has revealed that Imam is highly radicalised and believes that India should be an Islamic state.
In a video that has gone viral on social media, a group of anti-CAA protestors could be seen raising slogans against the Modi government inside what appears to be Delhi metro.
The Organisation of Islamic Cooperation (OIC) said it was "closely" watching the recent developments in India, including Parliament passing the Citizenship Amendment Act (CAA) and the verdict in the Ayodhya case.
