"The slogans attempted to incite the mob. These two persons, Umar and Anirban, led the crowd which shouted anti- Indian slogans. The police has also recovered two cellphones which established that anti-Indian slogans were raised by Umar and Anirban during the event," the prosecution said, adding that posters used for the event were recovered from the emails of two accused which shows that they were the main organisers of the event which took place even after permission was withdrawn by the JNU administration.
