Five men arrested near RAF Fairford released on bail as inquiry continues
Five British men arrested near RAF Fairford are being released on police bail as investigators continue to examine what happened outside the Gloucestershire airbase, the head of UK Counter Terrorism Policing said on Monday, September 28. Police have not established a motive or announced a foreign-state connection. Iran’s embassy in London has denied any link to the arrests.
The update changes the men’s custody status, not the status of the inquiry. Assistant Commissioner Laurence Taylor said the five remain under investigation and face stringent bail conditions governing their movements and contact with other people. Investigators are pursuing multiple lines of inquiry after interviewing the men and examining the vehicles in which they had been travelling.
What led to the arrests?
Gloucestershire Police received a report at about 12:45 a.m. on Sunday, September 27, concerning three vehicles travelling towards RAF Fairford. Armed officers responded and arrested the men in the nearby Whelford area. They were initially detained on suspicion of offences under the Explosives Act and were later also arrested on suspicion of preparing a terrorist act under Section 5 of the Terrorism Act.
Counter Terrorism Policing said all five are UK nationals who live in London. They are aged 23 to 25. The authorities have not publicly named them or announced charges. An arrest on suspicion of an offence does not establish that it occurred or that those arrested committed it.
Military personnel and forensic specialists have assisted with extensive examinations of the three vehicles. Police have not publicly set out what those examinations found, confirmed that viable explosives were present, or identified a specific intended attack. Those questions remain distinct from the offences officers are investigating.
What remains under investigation?
Police say they are working to establish the full circumstances of the men’s activity, what each person knew and any motivation. Taylor said investigators are keeping an open mind about whether the wider geopolitical situation has any bearing on the incident. One possibility under consideration is that people could have acted as proxies, knowingly or unknowingly, for a foreign state.
That is a line of inquiry, not a finding. Police have not identified a state as responsible or said that they have established a link between Iran and the five men. The men’s British nationality neither proves nor rules out any possible outside involvement. For now, the question of whether anyone else directed, assisted or knew about the activity remains unanswered.
Iran’s embassy in London rejected speculation connecting Tehran to the arrests. Its denial responds to suggestions of a link; it does not change the fact that UK investigators are examining several possible explanations. Describing the incident as an Iranian operation, or the arrests as proof of a foreign-backed plot, would go beyond what police have established publicly.
What is happening in Whelford?
The police operation has also disrupted residents near the vehicles. Gloucestershire Police initially established a 400-metre cordon and advised around 85 households to evacuate as a precaution while specialists examined the scene. A nearby leisure centre was made available to people who could not stay elsewhere.
In a later update on Monday evening, Gloucestershire Police said residents could return to their homes, although the cordon remained in place. Counter-terrorism officers were continuing their work at the location. The force asked the public to avoid speculation while inquiries continue and said it could not yet answer every question without risking the investigation.
RAF Fairford’s use by US military aircraft has drawn attention to the case amid wider tensions involving Iran. But the airbase’s role does not establish why the three vehicles were nearby or what the men intended. The next substantive answers will depend on the continuing examination of the vehicles, other evidence and any further decisions by investigators.
