Overview
- The police arrested five British men near the RAF Fairford base after a local woman reported three vans and masked figures during the night of Saturday to Sunday, September 26–27, and demining teams and a 400‑metre cordon led to the evacuation of about 80–85 homes.
- Counterterrorism officers formally treated the incident as a suspected preparation of a terrorist act and led searches and forensic work that continued through Monday and Tuesday.
- Police released the five men on bail with strict movement and contact conditions on September 29 while the investigation remains open and the suspects remain under inquiry.
- Several media reports say explosive‑ordnance experts did not find confirmed explosives in the three vans, a finding that has prompted public and political questions about the initial response and the evidence.
- Investigators are exploring multiple motives, including possible links to Iran that Tehran denies, while U.S. and U.K. officials stress close coordination as Fairford has hosted U.S. operations since March and local residents face ongoing disruption from cordons and evacuations.
