Hardeep Nijjar was first taken into custody by Canadian law enforcement in 2018 but was released within 24 hours. Nijjar was then represented by Sikhs For Justice (SFJ) legal advisor Gurpatwant Pannun, who is also wanted by the NIA and faces a red corner notice. Nijjar was closely associated with SFJ, officials said, adding he had participated in SFJ's 'Punjab Referendum 2020' conference.
