The Delhi Police on Sunday interrogated a student in connection with JNU student Umar Khalid’s whereabouts. 

According to sources, the student, Kamran, lives in South Delhi’s Munirka. The interrogation went on for more than six hours.

"Police also suspected him of being present at the JNU event when "anti-national" slogans were allegedly raised," sources said. 

Police may also contact some journalists, who had reported on the incident at the university. 

"On Sunday police might have contacted some journalists on phone or they might visited their homes to question them," sources added. 

Most of these journalists, including women, report on education and crime, and have been covering the various facets of the ongoing episode. Police are also checking the call records of Khalid through which investigators have got some of Khalid’s contacts. 

Sources said they tried questioning some of them for possible clues of their locations. 

Meanwhile, Delhi-based journalist Sadiq Naqvi was also interrogated on Sunday. 

Naqvi’s questioning began on 19 February when police reached his home in Uttar Pradesh. He was questioned at Vasant Vihar police station by a STF team for more than seven hours on Sunday, the third straight day. 

Khalid appeared on TV news channels defending the event, but chose to flee after Kumar’s arrest on charges of sedition and criminal conspiracy under sections 124-A and 120-B of the Indian Penal Code. 

His family members, relatives, friends and colleagues have also been questioned. Raids are also being conducted in Uttar Pradesh, Bihar, Maharashtra, West Bengal, Haryana and Jammu and Kashmir.
