Counter-terrorism police have made a new arrest in the RAF Fairford investigation, detaining a 25-year-old man holding both British and Iranian nationality. Fairford is the Gloucestershire air base used by US forces, and the man was detained in Westminster, London, on 1 October on suspicion of preparing terrorist acts. No one connected to the case has been charged, and police have not said what role they believe he played.
The arrest widens a case that has raised alarm among Western allies since the early hours of Sunday 27 September. It also lands at a politically charged moment: the UK government has said publicly that it believes Iran was involved, while Tehran calls the accusation baseless. What follows separates what police have established from what officials, governments and media reports have claimed.
What police have confirmed about the Westminster arrest
Counter Terrorism Policing announced the arrest in an update published on Thursday afternoon, saying the man was arrested on suspicion of preparation of terrorist acts under Section 5 of the Terrorism Act 2006, the law that criminalises steps taken toward carrying out an attack. Searches of two properties in the same area of London were also carried out.
Hours later the force corrected its own statement: the man is 25, not 27 as first published, and a line saying a second man had been questioned under caution was withdrawn as wrong. Several outlets still carry the earlier details, so HCN has used only the corrected version. The man has not been named, and police have not described the conduct he is suspected of.
How the RAF Fairford investigation began
Police were first alerted at about 12.45am on Sunday 27 September to three vehicles travelling towards the airbase, and a local farmer reportedly called in the suspicious vehicles. Five men were arrested in Whelford, a village about two miles from RAF Fairford, initially on suspicion of Explosives Act offences and then on suspicion of preparing a terrorist act once Counter Terrorism Policing took over. Police later said all five are British nationals aged between 23 and 25 and come from London. They were released on bail on Monday under strict limits on their movements and contacts, and they have not been charged.
Where the Iran claim stands
Prime Minister Andy Burnham told the BBC on Wednesday that there are strong indications Iran played a part, while stressing the police inquiry is still ongoing and complex. That is a government assessment, not a finding by police or a court. Counter Terrorism Policing has said it is examining every angle, including possible foreign-state involvement, and Assistant Commissioner Laurence Taylor said earlier this week that such activity may have been carried out by proxies, or by individuals acting knowingly or unknowingly for a foreign state.
Iran rejects the allegation. Its London embassy denied any link to the men arrested, its foreign minister, Abbas Araghchi, said Britain was looking in the wrong place, and Tehran summoned the British ambassador on Thursday. The dual nationality of the latest suspect is not, on its own, evidence of state involvement, and police have not said it is. The base itself explains why the question carries weight: according to CNN, US B-1 bombers have been flying missions against Iran from Fairford.
What is still unclear
Several basic questions remain open. Police have not publicly explained what the five men are suspected of intending, how the sixth suspect relates to the first five, or what link, if any, exists to a foreign state. Newsweek reported that US and UK accounts of how the incident began differ, and police have not specified whether the men were being watched before the farmer’s call. Charging decisions in terrorism cases in England and Wales rest with the Crown Prosecution Service, and none has been announced.
Until a charge, a court appearance or fuller police disclosure emerges, the Iran link remains an official belief rather than an established fact, and the five men on bail remain suspects, not defendants. HCN will update its coverage of the RAF Fairford investigation as verified information becomes available.
