Counter-terrorism police have made four arrests across East Sussex as part of an ongoing investigation into extreme right-wing terrorism.
Details of the Arrests
Specialist officers from Counter Terrorism Policing South East (CTPSE) carried out the operations on Thursday, 4 December 2025. The arrests took place in the coastal areas of Eastbourne and Brighton.
The individuals detained include a 27-year-old woman from the town of Hailsham. Three men from Eastbourne, aged 33, 36, and 41, were also arrested.
Legal Basis and Ongoing Activity
All four were arrested under the powerful Section 41 of the Terrorism Act 2000. This legislation allows for the detention of individuals suspected of involvement in terrorism without the need for an immediate warrant.
As of the latest reports, all suspects remain in police custody. Officers are concurrently conducting searches at a number of residential properties connected to the investigation.
Context and Public Response
While CTPSE has confirmed the operation is linked to extreme right-wing terrorism, specific details regarding the nature of the suspected activities or plots have not yet been disclosed to the public. The force has emphasised that the operation is part of a proactive and intelligence-led investigation.
Such operations highlight the continued focus of UK counter-terrorism units on addressing the threat posed by all forms of extremism. The public is advised that these arrests are a precautionary and investigative measure.
This remains a developing news story, with further updates expected as the police investigation progresses and searches are completed.
