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

Counter-terrorism officers have arrested a 22-year-old British national in central London as part of an ongoing investigation into a security incident near RAF Fairford, the Gloucestershire airbase that has recently found itself at the centre of heightened tensions involving the United States and Iran.

The man was detained in Westminster on Tuesday on suspicion of preparing terrorist acts, according to Counter Terrorism Policing. He is the seventh person taken into custody in connection with events that unfolded near the base on 27 September, though no charges have yet been brought against any of those detained.

The arrest marks a significant escalation in what police continue to describe as a live and fast-moving investigation. Vicki Evans, the senior national coordinator for Counter Terrorism Policing, confirmed that officers are "pursuing multiple lines of enquiry" and stressed that the case remains active. Her comments suggest that further arrests or developments have not been ruled out as detectives work through the evidence gathered over the past ten days.

The incident that triggered the investigation occurred in the early hours of 27 September, when police were alerted to three suspicious vehicles near the airbase. A major incident was declared, and dozens of homes in the surrounding area were evacuated as a precautionary measure. The disruption to local residents underscored the seriousness with which authorities treated the initial reports.

Five men were arrested that same day near the base. Aged between 23 and 25, they were detained in the early hours of the morning after vehicles were reported to be travelling towards the facility. They were initially arrested on suspicion of explosives offences before being re-arrested on suspicion of preparing a terrorist act. All five were subsequently released on police bail, a move that police characterised as an "investigative decision" grounded in experience and strategy rather than a sign that the threat had diminished.

A sixth suspect, a 25-year-old dual Iranian-British national, was arrested in Westminster on 1 October and was also released on bail pending further enquiries. The latest arrest on Tuesday brings the total number of people detained in connection with the case to seven, all of whom have been released without charge so far.

RAF Fairford, located near the village of Whelford, has been a fixture of American military operations in Europe for decades. The base has been used by the US Air Force for a range of missions, and in recent months it took on renewed strategic importance. Following the UK government's approval of a request for Fairford to be used for defensive strikes against Iran, the US flew B-1 and B-52 bombers from the base to the Middle East.

That deployment placed the base firmly within the broader geopolitical standoff between Washington and Tehran. However, on Sunday it emerged that the US had withdrawn its bombers from Fairford and returned them to America, a decision that raised immediate questions about the security situation on the ground.

US President Donald Trump addressed the withdrawal directly, telling reporters outside the White House on Monday that the aircraft had been removed because of "some threats" to the base. He declined to provide specific details but was unequivocal that the move was deliberate. "They didn't fly out by accident," Trump said. "There were some threats. And rather than tempting the enemy, we'll capture the enemy and beat the enemy. But why should we leave them there? So we moved them around a little bit. Not very far."

The US Vice-President, JD Vance, had earlier described the decision as one taken "out of an abundance of caution." His remarks, combined with Trump's comments, pointed to a genuine and specific concern about the safety of American assets stationed at the British base.

Those concerns appeared to be reinforced by US media reports suggesting that intelligence had indicated Iran was plotting a drone attack on the facility. The BBC has not independently verified those reports, and no official confirmation of the specific nature of the threat has been provided by either the UK or US governments.

Before Trump's intervention on Monday, a spokesperson for Number 10 had sought to reassure the public that RAF Fairford was safe. The spokesperson pointed to earlier comments in which the president had praised the UK's "police, defence and security services" in relation to the base, suggesting that close cooperation between the two allies remained intact.

The decision to withdraw the bombers nonetheless represents a notable development in the UK's relationship with the US over the use of British bases. Fairford has long been a linchpin of American air power projection, and its role in potential operations against Iran has made it a focal point of international attention.

British counter-terrorism officials now face the delicate task of establishing whether the arrests made in connection with the 27 September incident are linked to the broader threat picture involving Iran. The fact that one of the suspects is a dual Iranian-British national has fuelled speculation, though police have not drawn any public connection between the arrests and state-sponsored activity.

The investigation continues to unfold against a backdrop of heightened security awareness across the UK, particularly at military installations that host or support American forces. The evacuation of homes near Fairford served as a visible reminder of how quickly a localised security scare can escalate into a major incident with national and international ramifications.

For now, the seven individuals arrested in connection with the case remain on police bail, and no charges have been filed. Counter-terrorism officers have given no indication of when their enquiries might conclude, and the possibility of further arrests remains open. Vicki Evans's insistence that the investigation is "live" and that multiple lines of enquiry are being pursued suggests that the coming days and weeks could bring further developments in a case that has already drawn global attention.
