On a warm July Sunday, as thousands gathered for an Islamic religious event in the Suffolk countryside, police were racing to defuse what they would later describe as a 'potential serious threat' from far-right extremists. Within hours, 12 people were arrested across the country, and the event—the UK Ijtima at Shrubland Hall—was ended a day early to ensure safety.
The arrests, led by Counter Terrorism Policing London, followed what commanders said was intelligence about a suspected extreme right-wing terrorist plot targeting the gathering. Eight men were detained under section 41 of the Terrorism Act 2000, which allows police to hold terror suspects without charge. Three other men were arrested on suspicion of conspiracy to murder, and a woman on suspicion of assisting an offender. One of those men has since been released on bail; the rest remain in custody. Officers are conducting searches at multiple addresses linked to those detained.
“12 arrested in suspected far-right plot against Suffolk Islamic event; what it means for UK security.”
The UK Ijtima—an annual Islamic conference that draws families from across Britain—had been held at Shrubland Hall from 9 to 12 July. Police worked with organisers to close the event slightly ahead of schedule on Sunday 12 July, ensuring it passed off safely. Commander Helen Flanagan, head of Counter Terrorism Policing London, said: 'I know this news may be concerning to the public and particularly those in the Muslim community, given that we believe the intended target was an Islamic event. But as we have shown, we will not hesitate to act if there is any potential threat, no matter who or what the potential target may be.'
The case is a stark reminder that the UK's national terror threat level remains at 'severe', meaning an attack is highly likely. Far-right extremism has become an increasing focus for counter-terrorism policing in recent years, and this investigation shows how quickly authorities can mobilise when a credible threat emerges. For Muslim communities in particular, such incidents can heighten anxiety—but the police response here was designed to demonstrate that protection is available to all.

Q: What should the public do if they see something suspicious? Commander Flanagan urged vigilance, saying: 'We urge the public to remain vigilant and report anything if it doesn't look or feel right.' Information can be reported via the ACT website or by calling the confidential Anti-Terrorist Hotline on 0800 789 321. In an emergency, always dial 999.
The investigation is ongoing, led by Counter Terrorism Policing London with support from regional units. Searches continue at addresses across the country. While the immediate threat appears to have been contained, authorities stress the importance of public vigilance as the threat level remains severe.
