Gurpatwant Singh Pannun is known for his association with the legal advocacy group "Sikhs for Justice" (SFJ). Please note that my information might be outdated, and there could have been developments since then.

Sikhs for Justice is an organization that has advocated for the right to self-determination for the Sikh community in India, particularly supporting the idea of an independent Sikh state called Khalistan. The Indian government has labeled SFJ as a secessionist and unlawful organization.

Gurpatwant Singh Pannun, as of my last update, has been one of the key figures associated with SFJ and has been involved in legal efforts to promote the cause of Khalistan. It's advisable to check more recent sources for any updates or changes in his activities or the status of Sikhs for Justice.

US officials have reportedly averted a plot to murder Sikh separatist leader Gurpatwant Singh Pannun. The Sikhs for Justice chief is designated as a terrorist in India and had recently come under the scanner for ‘threatening’ Air India passengers. The White House said that it had taken the matter up with Indian authorities at the highest levels “with utmost seriousness".

“We are treating this issue with utmost seriousness, and it has been raised by the U.S. Government with the Indian Government, including at the senior-most levels. Indian counterparts expressed surprise and concern," National Security Council spokeswoman Adrienne Watson said in a statement.

Meanwhile, Indian authorities said in a statement that the US side had “shared some inputs" about terrorists and organized criminals that were a “cause of concern" for both countries. New Delhi said that they had “decided to take necessary follow-up action". The development also comes two months after Canadian Prime Minister Justin Trudeau claimed there were “credible allegations" linking the Indian government to the death of another Sikh separatist leader – Hardeep Singh Nijjar.

According to a Financial Times report citing unnamed sources, US federal prosecutors have also filed a sealed indictment against at least one alleged perpetrator of the plot. The publication cited one person familiar with the matter to add that one person charged in the indictment is believed to have left the US.
