Two Latvian men arrested at RAF base in Cambridgeshire used by US military

Two Latvian men were arrested in the early hours of Thursday after they were discovered inside the perimeter of RAF Molesworth, a Cambridgeshire base used by the US military and Nato for intelligence operations.

The men, 32 and 36, were picked up at 2am inside the base in an investigation that began four hours earlier when military police discovered an abandoned vehicle outside the facility.

Soon after military police, helped by officers from Cambridgeshire police, discovered a small hole in the perimeter fence before finding and arresting the men, initially on suspicion of trespass on a prohibited site and causing criminal damage.

The suspects, Latvian nationals currently resident in the UK, were then further arrested on suspicion of an offence under section 4 of the National Security Act 2023 – namely entering a prohibited place for a purpose prejudicial to the UK.

Counter-terror police are now leading the investigation due to the nature of the incident, which comes a few days after the US withdrew B-1 bombers from RAF Fairford in Gloucestershire amid concerns about a possible Iran-directed attack.

Cmdr Helen Flanagan, head of counter-terrorism policing London, said there was nothing to suggest a connection to last month’s incident near RAF Fairford at this stage, but said investigators were yet to determine what the men were doing.

“Our investigation into this incident is at its very early stages. 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 inquiries are very much ongoing,” she added.

The abandoned vehicle was taken to a nearby police location. Initial searches led concerned officers to call in explosives specialists to carry out further checks. A police cordon was briefly imposed on part of the A1 south of Peterborough and around the village of Glatton, but nothing of concern was found.

Officers are carrying out two searches at addresses in the Peterborough area in connection with the investigation, counter-terror police added in a statement. Both men remain in police custody.
