British counter-terrorism police arrest 12 people over a suspected far-right terrorism threat aimed at an Islamic event in Suffolk, held over the weekend at Shrubland Hall. Multiple outlets report that investigators describe the case as relating to “extreme right-wing” terrorism. Police say some of the arrests are connected to an alleged plot concerning the event, and the investigation is led by counter-terrorism officers.
The Guardian reports that three of those arrested are detained on suspicion of conspiracy to murder. Other reporting describes the arrests as taking place across parts of southern and eastern England, with one person detained in Greater Manchester. The BBC and other outlets also report that the Islamic event ends early on Sunday due to concerns about a possible threat.
Reuters and other summaries describe the threat as credible or possible but do not provide additional public details about specific targets or plans. Police have not publicly named those arrested in the accounts provided, and the allegations remain subject to ongoing investigation.
