Home Secretary and Counter Terrorism Policing stressed the credible threat, pledged decisive action to protect communities, and urged vigilance while the investigation continues.

Senior officials emphasized unity against hatred, public reassurance, and the importance of reporting anything suspicious during an ongoing investigation.

The inquiry remains ongoing, led by CT Policing with multiple agencies coordinating in the response to the threat and subsequent arrests.

Intelligence prompting the arrests emerged over the weekend, with late interventions during the event, road closures, and misinformation circulating on social media.

Following a credible right‑wing threat, twelve people were arrested across the UK and the large Islamic event at Shrubland Hall in Suffolk ended early as a precaution, with eight men detained under section 41 and three others (aged 82, 55, and 60) arrested on suspicion of conspiracy to murder.

Police declared a major incident and carried out rapid, multi‑location arrests to protect about 15,000 attendees, coordinating with counter-terrorism and other agencies.

Authorities urged the public to report anything suspicious and thanked organisers, police, and the public for swift action that helped prevent harm.

With the UK threat level remaining severe, officials emphasized ongoing vigilance and continued reporting of suspicious activity.

Assistant Chief Constable Alice Scott said a visible police presence would reassure Shrubland Hall residents in the coming days, and the major incident status was later withdrawn.

The event finished slightly earlier than planned, guided by organizers and officials to ensure safe departures, while authorities pledged sustained visible policing and community reassurance, including for the Muslim community.

Local officials and Councillor Ruman Muhith noted there was no panic on site and attendees were informed of the early finish after the morning prayer.

Counter Terrorism Policing, with support from Suffolk Police, stated they acted quickly to make arrests and declare a major incident as part of a coordinated response.
