RAF Fairford Inquiry: Sixth Suspect Bailed as Police Examine Foreign-State Angle
A 25-year-old dual UK-Iranian national arrested on suspicion of preparing terrorist acts linked to an alleged plot against RAF Fairford has been released on bail.
Counter Terrorism Policing confirmed the release on 3 October 2026 and said the investigation remains active. The man had been detained on 1 October in Westminster, London, on suspicion of an offence under Section 5 of the Terrorism Act 2006. That is the law that covers planning or preparing a terrorist act, not only carrying one out. The Guardian Searches of two properties linked to him have concluded.
He was the sixth person arrested in the inquiry. Five British nationals in their mid-20s were arrested last weekend on suspicion of explosives offences and terrorism and were then bailed. Police said the five were arrested in Whelford on the morning of Sunday 27 September, and confirmed on 1 October that they remained on police bail.

The arrests followed the spotting of three suspicious vans near RAF Fairford in Gloucestershire. Counter-terrorism police said a quantity of petrol but no explosive devices was found in the vans.
Vicki Evans, senior national coordinator for Counter Terrorism Policing, described the investigation as "hugely complex." She said police were examining all possible angles, including possible foreign state involvement.
Political leaders have responded to that suggestion of state involvement. Prime Minister Andy Burnham said there were strong indications Iran played a part in the incident near RAF Fairford. U.S. Secretary of State Marco Rubio said the incident involves a "foreign actor." BBC

He said Israel warned UK authorities about an Iranian-sponsored attack shortly before Britain announced a ban on trade with illegal Israeli settlements in the West Bank. Iran condemned "malicious speculation" about its alleged role. Al Jazeera
RAF Fairford has been used in recent months by U.S. bombers after former Prime Minister Keir Starmer granted Washington permission to use British bases for defensive strikes against Tehran.
The broader context here is that the policing facts so far are narrow and the political claims are wide. Police have disclosed vans, petrol, no devices, six arrests and six bails. No charges have been announced. Bail in terrorism inquiries lets police continue work such as forensic tests and review of seized material, while placing limits on suspects' movements.
Looking at what this means for investigators, the Section 5 arrest is a distinct strand from the initial explosives-related arrests. Preparation of terrorist acts covers intent and planning as well as holding materials. The decision to arrest a sixth suspect days later in London, rather than near the Gloucestershire site, points to lines of inquiry beyond the vans themselves. That fits Evans's language on complexity, though police have not detailed what those lines are.
For policymakers, the picture right now is attribution without charges. Burnham's language on Iran, Rubio's reference to a foreign actor and Netanyahu's claim of an Israeli warning all frame the vans as state-linked. Tehran rejects that account. Intelligence sharing, public attribution and legal proof run on different timelines and to different standards. A political assessment of strong indications can sit for weeks or months alongside a police inquiry that has yet to gather enough evidence for prosecution.
What to watch next is procedural. Police will determine whether to re-arrest, extend bail, apply for further search or detention powers, or submit a file to prosecutors. Any shift from petrol and vans to evidence of direction, funding or tasking would change the legal and diplomatic character of the case. Until then, the Fairford inquiry sits on two tracks: a counter-terrorism investigation still gathering evidence, and a diplomatic dispute over Iran, U.S. use of British bases and the UK-Israel relationship in which each statement carries weight beyond the courtroom.
