Two Latvian nationals residing in the United Kingdom were arrested inside the perimeter of RAF Molesworth in Cambridgeshire following a security breach that triggered a counter-terrorism investigation. The suspects, aged 32 and 36, were detained at approximately 2 a.m. on Thursday, October 8, after military police and local constabulary discovered a small cut in the base’s perimeter fence.
Timeline of the Security Breach at RAF Molesworth
The sequence of events began at roughly 10 p.m. on Wednesday when a Ministry of Defence Police (MDP) security patrol spotted an abandoned vehicle parked near the exterior of the military installation. Following joint searches conducted by the MDP and the Cambridgeshire Constabulary, authorities identified a physical compromise in the perimeter barrier a few hours later.
Officers located both suspects deep within the base boundaries and initially took them into custody on preliminary complaints of trespassing on a prohibited site and committing criminal damage. They were transported to a local Cambridgeshire police station for questioning as the investigation widened.
Escalation Under the National Security Act 2023
As the probe progressed, counter-terrorism specialists stepped in to lead the inquiry. Detectives upgraded the legal basis for the detention, arresting the two Latvian men under Section 4 of the National Security Act 2023. This specific statute addresses the offense of entering a prohibited place for a purpose considered prejudicial to the safety or interests of the United Kingdom.
Commander Helen Flanagan, head of Counter Terrorism Policing London, issued a statement addressing the early nature of the inquiry and potential underlying motives:
A big part of this is looking at any potential motivation as to why the men were present at the site, but I must stress we are keeping an open mind at this stage and enquiries are very much ongoing.
In connection with the ongoing probe, counter-terrorism officers executed searches at two separate residential addresses located in the Peterborough area. Meanwhile, explosive ordnance disposal (EOD) teams were deployed as a precaution to inspect the abandoned vehicle that originally prompted the security alert. Part of the A1M and neighboring roads in the Glatton area experienced temporary cordons and closures, though authorities lifted restrictions shortly after midday on Thursday when inspections revealed nothing of concern.
Strategic Importance of the Military Facility
RAF Molesworth holds high strategic value as a joint military intelligence installation. The facility houses key operational command units for the United States Air Force’s 423rd Air Base Group, functions as a primary hub for US military intelligence in Europe and Africa, and accommodates the North Atlantic Treaty Organization (NATO) Intelligence Fusion Centre.
In 2024, the US Defence Intelligence Agency broke ground on a massive $556 million (£421 million) upgrade project at the base to further consolidate intelligence operations. Given the sensitive nature of the site, defense spokespersons reiterated that installation protection relies on a continuous, multi-layered defense strategy.
Investigation Context and Independent Incidents
Security officials have explicitly noted that there is currently no evidence linking the breach at RAF Molesworth to a separate high-profile security incident that unfolded the previous week at RAF Fairford in Gloucestershire. While investigators maintain an open perspective regarding foreign threats or coordinated efforts targeting British defense sites, authorities have urged local residents and the broader public to remain vigilant and report suspicious behavior immediately.
