Today we questioned several protesters and also some police officials who were seen standing close to the two unidentified men in civil dress. However, none of them has so far been able to identify the two men, a police source said.
Joint Commissioner of Police (Central) S K Gautam, who has to submit a report on the incident to Police Commissioner B S Bassi, said the two are yet to be identified but the process is on.
Yesterday, Lt Governor Najeeb Jung had summoned top brass of Delhi Police and directed them to promptly probe the incident.
Delhi Police came under severe attack from various quarters after a video of some policemen thrashing a group of students, including women, during a protest on January 30 over Dalit research scholar Rohith Vemula's suicide went viral on social media.
