The police filed the supplementary charge sheet on September 26 before Chief Metropolitan Magistrate Purushottam Pathak against nine persons in the case related to the alleged murder of Hashim Ali during the riots in Gokulpuri area.

"As per the chat of Whatsapp group, the accused persons... conspired to teach Muslims a lesson for attacking the Hindus. Equipped themselves with lathis. danda, sticks, swords, firearms etc and killed nine innocent Muslims persons including Hashim Ali and his brother Aamir Khan. It is prima facie revealed that there was a well hatched conspiracy amongst the accused persons. "Same is also evident from the fact that in order to take revenge from Muslims some youths of that area who failed to perceive the bottomless stupidity of the propaganda, they as saviours of their community created a Whatsapp group. The group members lost their individuality and started working with mob mind. 'Jai Sri Ram' and 'Har Har Mahadev' which are the sacred slogans and are attached to the victorious yelling, deaden their mind and paralyzed their creative nature. They planned the manner of committing offence of rioting, murder and other offences...," police alleged in the charge sheet. In the supplementary charge sheet, police has booked the accused under sections 153-A (promoting enmity between different groups on grounds of religion, race, place of birth, residence, language etc) and 505 (public mischief) of the Indian Penal Code for allegedly assembling to take revenge against the other community and targeting the victims on the basis of their religious identity.

"During the investigation and from the report of retrieving data of seized mobile phones revealed that the above mentioned report/result of Whatsapp group 'Kattar Hindu Ekta', group, it is also clear that there are averments in respect of promoting enmity between different groups on the ground of religion and acting in a way that are prejudicial to the maintenance of harmony," the charge sheet claimed.

It claimed that the mob turned rioters and allegedly murdered Ali by inflicting multiple injuries in a brutal manner and with a view to conceal the evidence, all of them in furtherance of their common intention threw his dead body in the drain.
