British counterterrorism police released all five RAF Fairford suspects on bail on September 28 while keeping the investigation open and imposing stringent movement and contact conditions. [S2][S3]
The men had been arrested near the base on September 27 on suspicion of terrorism and explosives offenses after three suspicious vehicles were seen approaching RAF Fairford. [S2][S5]
The releases raised new questions about the alleged plot, while separate reporting said whether Iran had any role remained an open question. [S1][S2]
Police said they were considering whether foreign-state proxies or individuals were involved, while Iran’s embassy categorically rejected speculation linking Iran to the incident. [S2][S4]
The Guardian reported that no explosive material had been found. [S1]
Verification result: verified, because none of the material claims is contradicted in the supplied record and at least two independent reporting families directly support the central claim. [S1][S2]
The suspects’ intent, whether any viable device existed, and any Iranian role remain unresolved because officials had not disclosed firm evidence and Iran denied involvement. [S1][S2][S4]
