Harman Singh Kapoor, a Sikh restaurant owner in London, has claimed that he & his family is receiving constant online threats after they posted a video about the Khalistan movement on social media. His restaurant was attacked by pro-Khalistani supporters, which came days after the Indian High Commission in London was vandalized On March 19. A group of pro-Khalistan supporters vandalised the Indian High Commission and shattered windows, destroyed doors, got on the balcony and pulled the Indian flag down.

Harman said that the threats began after he posted a video on TikTok, in which he said, "This Khalistan movement started a while back and then it died down. Today again, a section of people who are settled in Canada, in England and Australia want Khalistan, but those in India don't want it." Harman said that following the video, he received death threats and his restaurant was attacked. Harman and his family -- wife Khushi and two children -- alleged that they have been attacked three times, repeatedly trolled on social media and intimidated by abusive calls. They claimed their car was being followed since he posted the video where he asked the people to make calls for Khalistan to be made in India and not in foreign countries like the United Kingdom or Canada. Harman alleged the attackers asked him to remove the post and raise slogans like "Khalistan Zindabad" and "Hindustan Murdabad". They also told him to burn India’s flag or else he would be killed. He claimed the police did come and assured us of our safety

An independent report commissioned by former UK Prime Minister Boris Johnson has expressed concerns over the rising influence of pro-Khalistan extremists within the British Sikh community. The Bloom Review, an independent report commissioned by former UK Prime Minister Boris Johnson, has called on the Rishi Sunak government to address the issue urgently and safeguard most of the Sikhs in the UK who do not support the extremist ideology. The report noted that the Sikh communities in the UK face oppression and intimidation by fringe Khalistani elements. As per the report, these pro-Khalistan groups artificially inflate their influence and attract disproportionate attention by lobbying political bodies under the guise of human rights activism.
