Earlier today, Kejriwal met the President to seek his intervention into the matter.
Speaking to the media here after meeting with the President, Kejriwal had pinned the blame on Delhi Police, accusing them of refusing to take action after coming under political pressure.
Meanwhile, the Delhi Police detained the students of Jawaharlal Nehru University (JNU), who were staging protest against the authorities at the India Gate here for not taking firm steps to locate their missing colleague Najeeb Ahmed.
Najeeb's sister Sadaf Mosharraf, who was also among those detained by the police, vented her ire at the men in uniform.
""We were protesting very peacefully but the Delhi Police detained us without any reason," she said.
Chief Minister Arvind Kejriwal on Sunday alleged that the Centre was adopting 'dictatorship' policy and violating the constitutional right of an individual by adopting such measures.
"Why is the Prime Minister afraid of protests? If one student is missing since the last 22 days then other students have the right to protest. This is their constitutional right and the government is trying to snatch their rights from them," said Kejriwal.
Commenting on the Delhi Police's move to summon nine people in connection with this case, Kejriwal said that the men in uniform have just done a formality in the name of investigation.
"The BJP is ruling the nation and Delhi Police is afraid of the Akhil Bharatiya Vidyarthi Parishad (ABVP). So, they didn't have the courage to call the ABVP people from past 22 days and just for formality they called few ABVP members for interrogation yesterday," he said.
Last week, Kejriwal had made a beeline to the JNU campus along with other party leaders to take on the Centre over the missing student.
"The way the country has progressed in the last two years is of grave concern. Today Najeeb is missing. Tomorrow my son can go missing," Kejriwal then said.
Najeeb went missing on the intervening night of October 14 and 15 after allegedly being beaten up by a mob of 20 students comprising of the ABVP members, who had gone campaigning to his room for hostel elections.
