British counter-terrorism officers arrested a 27-year-old dual UK–Iranian national in Westminster on Wednesday on suspicion of preparing terrorist acts linked to the security scare at RAF Fairford, and questioned a second man under caution as the sprawling investigation into last weekend’s incident near the U.S. bomber base entered a new phase.
What police disclosed
The BBC reported the arrest and questioning early Thursday, citing Counter Terrorism Policing. Officers searched two properties in the Westminster area, the broadcaster said, without naming either individual—standard practice while charges are not filed.
The development follows a chain of detentions after Gloucestershire police were alerted to suspicious vehicles near Fairford in the early hours of last Sunday. Five British men in their twenties were arrested near the base on suspicion of explosives and later terrorism offences, then released on bail earlier in the week as detectives widened the net to London.
Why Fairford is in the spotlight
RAF Fairford in Gloucestershire has served for decades as a forward location for U.S. Air Force bombers, including B-1 aircraft that participated in strikes on Iran during the expanded Middle East war. Security around the base tightened after Iranian officials warned that British facilities used against Tehran could be treated as legitimate targets.
Prime Minister Andy Burnham told reporters there were “strong indications” Iran played a part in the Fairford incident, while stressing the inquiry remained complex. Iran’s embassy in London has denied involvement. The U.S. moved a dozen B-1 bombers out of Fairford after intelligence suggested a possible drone plot, according to reporting from U.S. and British outlets.
Investigative timeline
Police declared a major incident last weekend and evacuated dozens of homes after farmers and emergency callers reported masked men and vans near the airfield. One line of inquiry explored whether a 999 call placed about an hour before the farmer’s alert was connected to the group later detained in Whelford.
A separate dual national arrested on 1 October on the same terrorism preparation suspicion was released on bail on 3 October after searches concluded, Reuters reported. Thursday’s Westminster arrest suggests detectives are still pursuing associates rather than closing the file.
Political and security fallout
Burnham chaired a Cobra emergency meeting after the initial arrests, and opposition parties have pressed for clearer public accounting of how drone threats are monitored around allied bases on UK soil. Conservative leaders separately unveiled proposals for layered air-defence systems after the Fairford scare highlighted gaps in protecting high-value aircraft far from traditional front lines.
For residents near Fairford, bail conditions on earlier suspects and the continuing London searches mean disruption may linger even as the base resumes flying schedules. Counter Terrorism Policing said the Gloucestershire investigation is ongoing and asked the public to report anything suspicious around military installations.
What comes next
None of the men arrested has been charged publicly, and prosecutors will decide whether the evidence meets thresholds for terrorism preparation counts under the 2006 Act. Further court hearings or bail variations could come with little notice given the national-security sensitivity.
Until then, the Fairford case remains a test of how quickly UK authorities can connect rural intrusion alerts with London networks—and how openly ministers can discuss suspected foreign direction without prejudicing trials.
