Two Latvian nationals legally residing in the United Kingdom were arrested on October 9, 2026, under Section 4 of Britain’s National Security Act of 2023 after allegedly breaching a perimeter fence at RAF Molesworth, a British military base that houses critical US and NATO intelligence operations, according to Reuters. The arrests initiated a counterterrorism investigation into the security breach at this strategic installation, which supports American military commanders across Europe and Africa.
The base is currently undergoing a $556.5 million expansion focused on the Joint Intelligence Analysis Complex (JIAC), which is designed to consolidate 20 intelligence facilities and accommodate over 1,000 personnel. The suspects, aged 32 and 36, were found inside the base around 2 a.m. after a security sweep.
Ministry of Defense Police officers had raised the alarm around 10 p.m. the previous night after discovering an abandoned vehicle near the perimeter. Bomb disposal specialists cleared the vehicle before armed officers found the fence breach and located the two men inside. Initially detained on suspicion of trespass and criminal damage, both men were later arrested under the National Security Act for allegedly entering a prohibited area for a purpose prejudicial to the United Kingdom. They remain in custody as counterterrorism detectives execute search warrants at two residential properties in nearby Peterborough.
Managed by the US Air Force’s 423rd Air Base Group, RAF Molesworth is a non-flying installation dedicated to joint intelligence and command operations, housing elements for US European Command, US Africa Command, and the NATO Intelligence Fusion Centre. The airfield was used by the US 15th Bombardment Squadron during World War II and was officially deactivated in 1973 before transitioning to its current role as an intelligence center.
Construction on the JIAC began on April 12, 2024, with onsite work starting that spring and scheduled for completion in summer 2028. A 2024 Defense Department release described the base development as part of the department’s European Infrastructure Consolidation efforts. The facility will combine 20 facilities and over 1,000 Defense Intelligence Agency personnel into one location, hosting members from various military and intelligence agencies.
Following the intrusion, US European Command commended the rapid response from British authorities, stating, "While we assess the global security posture, US forces remain at the highest state of readiness," and expressed gratitude for the close partnership with UK forces on security matters. British counterterrorism officials advised caution against making premature conclusions regarding possible espionage or terrorist motives. Counterterrorism Policing London commander Helen Flanagan noted that investigators have not established a connection between the Molesworth breach and recent security concerns at RAF Fairford, another British base used by US strategic bombers, stating, "We are keeping an open mind at this stage and inquiries are very much ongoing."
