A court in has granted one more month to Delhi police to complete its probe in a case against the president of Alumni Association of Jamia Millia Islamia who was arrested under the stringent Unlawful Activities (Prevention) Act (UAPA) in connection with the riots in northeast Delhi in February.

The police said that the co-conspirators are yet to be arrested and the efforts were being made to identify and apprehend them.
"Their apprehension is crucial in finding out the missing links of the larger conspiracy.... In the present case, several layers of conspiracy have surfaced and to unearth the deep rooted conspiracy, interrogation of remaining is important for the purpose to investigate the present case from all possible angles.
"Search of other co-accused persons of this case is going on but due to lockdown COVID-19 period, process of searches in other states is hindered," the police told the court.

"Moreover, bills were created to manage that suspicious fund. The persons concerned, related to these bills, are being examined but due to pandemic COVID-19, process of getting details and examination of witnesses is slow," it said.
Police told the court that apart from 23 protest sites reporter earlier, two more protest sites have also been identified which were brought up as a part of conspiracy for riots.
"All the sites were managed, controlled and organized by multiple layer teams in a well-structured and systematic manner. Each individual layer team has been assigned role to perform in furtherance of executing the conspiracy.
"The investigation regarding identification of the persons involved in this deep rooted conspiracy and their role in furtherance of conspiracy is being minutely under investigation," it said.
During the course of investigation conducted so far, role of Sharjeel Imam has also surfaced in the hatching of the conspiracy of this case, police said.
It told the court that Imam has been declared coronavirus positive, which has also "derailed the investigation to a huge extent".
In the FIR, police have claimed that the communal violence was a ''premeditated conspiracy'' which was allegedly hatched by former JNU student leader Umar Khalid and two others.
