Seventh Arrest Made in RAF Fairford Terror Probe as US Bombers Leave Base

Counter-terrorism officers have detained a 22-year-old British man in central London as part of an ongoing investigation into a security incident near RAF Fairford, the US Air Force base in Gloucestershire that has become the focus of intense scrutiny in recent weeks.

The arrest took place in Westminster on Tuesday, according to Counter Terrorism Policing, which said the man was held on suspicion of preparation of terrorist acts. He is the seventh person to be detained in connection with events that unfolded in the early hours of 27 September, when police responded to reports of suspicious activity close to the airfield.

No charges have yet been brought against any of those arrested, and detectives have stressed that the inquiry remains active. Senior national coordinator for Counter Terrorism Policing, Vicki Evans, confirmed that officers are continuing to "pursue multiple lines of enquiry" and described the case as a "live investigation."

The incident began when police were alerted to three "suspicious vehicles" near the base. The response was rapid and substantial: a major incident was declared and dozens of homes in the surrounding area were evacuated as a precaution. The disruption marked one of the most significant security scares linked to a UK military installation in recent months.

Five men were arrested near the base on the same day. Aged between 23 and 25, they were detained in the early hours after reports that vehicles were travelling towards the airfield. Initially held on suspicion of explosives offences, they were later arrested on suspicion of preparing a terrorist act. All five were subsequently released on police bail, a decision police characterised as an "investigative decision" that was "grounded in experience and strategy."

A sixth suspect, a 25-year-old dual Iranian-British national, was arrested in Westminster on 1 October and later released on bail, adding a further international dimension to a case that has attracted attention on both sides of the Atlantic.

RAF Fairford, situated near the village of Whelford, has been a fixture of American air operations in Europe for decades. In recent months, the base took on heightened strategic importance after the UK government approved a US request for it to be used for defensive strikes against Iran. B-1 and B-52 bombers were flown from Fairford to the Middle East as part of that arrangement, placing the site at the centre of wider tensions between Washington and Tehran.

That prominence appeared to carry direct consequences. On Sunday, it emerged that the US had withdrawn its bombers from the base and returned them to America. President Donald Trump said the aircraft had been removed because of "some threats" to the installation, though he did not provide specific details about their nature or origin.

Speaking to reporters outside the White House on Monday, Trump was asked whether a "specific threat" had prompted the withdrawal. He responded: "Yeah I think we can say that. They didn't fly out by accident." He added that there were "some threats" and that rather than tempting the enemy, the US would "capture the enemy and beat the enemy," before noting that the aircraft had been moved "around a little bit. Not very far."

US Vice-President JD Vance had earlier said the bombers were relocated "out of an abundance of caution," a phrase that sought to balance operational security with public reassurance. The comments followed US media reports suggesting the decision was made after intelligence indicated Iran was plotting a drone attack, although the BBC has not been able to verify those reports independently.

Before Trump's intervention, a Downing Street spokesperson had insisted that RAF Fairford was safe, pointing to the president's earlier praise of the UK's "police, defence and security services" in relation to the base. The contrasting statements illustrate the delicate balancing act faced by officials when security concerns intersect with diplomatic sensitivities involving allied nations.

The sequence of events — a major security incident, multiple arrests, the evacuation of local residents and the sudden departure of US strategic aircraft — has raised questions about the threat environment surrounding UK bases used by American forces. Counter-terrorism investigators have not publicly linked the arrests to any state actor, and the precise motivation behind the suspected activity near Fairford has not been disclosed.

For residents in the villages around the airfield, the past fortnight has brought an unusual degree of disruption and uncertainty. The evacuation of dozens of homes, even as a precaution, represents a significant imposition in a rural area unaccustomed to such large-scale security operations. The decision to release all suspects on bail while inquiries continue may also prompt local concern, though police have defended their approach as methodical rather than rushed.

Legal experts note that "preparation of terrorist acts" is a serious offence under UK counter-terrorism legislation, carrying substantial penalties if proven. However, they also caution that arrests at this stage reflect suspicion rather than evidence of guilt, and that lengthy bail periods are common in complex investigations where detectives must sift through large volumes of material before determining whether charges are viable.

The international backdrop adds further complexity. With Fairford having hosted bombers tasked with operations connected to Iran, any suggestion of Iranian involvement would carry profound diplomatic implications. Tehran has not commented publicly on the reports, and officials have been careful not to attribute the alleged threats to any particular source while the investigation proceeds.

Counter-terrorism commanders continue to appeal for anyone with information to come forward, and have indicated that further arrests or developments cannot be ruled out. The investigation now spans multiple strands, multiple suspects and at least two capital cities, with the 22-year-old arrested in Westminster the latest piece in a puzzle that investigators are still assembling.

What remains clear is that RAF Fairford — a base that has quietly served American air power for generations — has become an unexpected focal point for questions about security, intelligence-sharing and the risks that come with hosting strategic assets in an era of heightened global tension. How the investigation unfolds in the coming weeks will determine whether those questions lead to charges, or to a broader reassessment of how such bases are protected.
