Police have arrested four suspects from East Sussex as part of an investigation into extreme right-wing terrorism, officers say.

Counter Terrorism Policing South East (CTPSE) say have been carrying out property searches after making arrests in Eastbourne and Brighton on Thursday.

Officers arrested a 27-year-old woman from Hailsham and three men aged 33, 36 and 41 from Eastbourne as part of the “intelligence-led operation”, a CTPSE spokesperson said.

Sussex Police Assistant Chief Constable Steve Rayland says he is aware such investigations “can cause people in the local community to feel concerned”, but the arrests “form part of a planned operation to keep people in our communities safe”.
