US Army Soldier Arrested in UK on Suspicion of Russia Spying

A 41-year-old member of the US Army was arrested near Gloucester on Tuesday, 10 November, on suspicion of offences under Section 1 and Section 3 of the UK’s National Security Act 2023, the Metropolitan Police said. “The country to which the allegations relate is Russia”, the statement said.

NATO’s Allied Rapid Reaction Corps said in a statement that the American service member arrested by British police “was assigned to NATO’s Allied Rapid Reaction Corps (ARRC)”. The man has not been named, and the police statement announces an arrest, not a charge.

A short general explainer on least privilege, giving each person only the access their role needs. It does not discuss this case, the Army or NATO.

What the Police Said

Counter Terrorism Policing is leading the investigation, “working closely with US authorities, US Military and the FBI”, the Met said. Officers are carrying out searches at two locations in Gloucestershire. The man “currently remains in custody at a London police station”, and the investigation is led by officers from CTP London.

The statement says the investigation is not linked to any other ongoing Counter Terrorism Policing investigations. NBC News and CBS News reported that Sections 1 and 3 relate to obtaining or disclosing protected information and to assisting a foreign intelligence service.

Deputy Assistant Commissioner Vicki Evans, Senior National Coordinator for Counter Terrorism Policing, said: “The allegations are serious and our investigation is very much ongoing”.

What Was Posted on X

The account @PolitlcsUK posted at 18:53 UTC on 10 November that a serving member of the US Army had been arrested in the UK under the National Security Act on suspicion of spying for Russia. The Metropolitan Police statement of the same evening confirms an arrest on suspicion of offences under Sections 1 and 3 of the National Security Act 2023, with the allegations relating to Russia; this piece is built on that statement.

What the US Officials Said

FBI Director Kash Patel said in the same statement: “This important arrest involves allegations of espionage, which is of the utmost concern to the United States and our allies”. He also said: “This includes 167 counterintelligence and espionage arrests from this FBI over the last 21 months – a 53% increase”. The statement does not give the baseline for the increase.

Brig. Gen. Sean Stinchon, commanding general of US Army Counterintelligence Command, said the “alleged conduct of a senior solider, entrusted with sensitive information, is a sobering reminder that insider threats are real and persistent”. The statement prints “solider” as written.

Where He Served

ARRC says the service member was assigned to its corps and referred further enquiries to UK and US authorities. Three people familiar with the matter told NBC News that the soldier was based at the Allied Rapid Reaction Corps headquarters at Imjin Barracks, on the outskirts of Gloucester. A US official told CBS News he is a senior officer based at Imjin Barracks.

CNBC described ARRC as a 3-star NATO headquarters with more than 400 permanent staff from more than 20 nations. On 27 October, CNBC reported, British prosecutors charged a man with assisting a foreign intelligence service over an incident at RAF Fairford, also in Gloucestershire; police said the new case is not linked to other ongoing investigations.

The Structural Read

As we read the Met statement, the two sections cited separate two alleged acts, handling protected information and assisting a foreign intelligence service, and both are suspicions at the arrest stage.

As we read it, the officials’ own words stress the partnership between UK and US agencies as much as the case itself; none of the statements describes what was allegedly passed or to whom.

Three Implications

FOR THE CASE The man remains in custody at a London police station and enquiries continue, the Met says.

FOR NATO ARRC confirmed the assignment and referred further enquiries to UK and US authorities.

FOR THE FBI Patel cited 167 counterintelligence and espionage arrests over 21 months, which he called a 53% increase.

What Is Not Established

The man’s name, rank and role have not been released in the official statements we read; the “senior officer” and Imjin Barracks details come from people who spoke to NBC News and CBS News. The statements give no detail on what information is alleged to be involved. An arrest on suspicion is not a charge, and nothing in the statements we read says when a charging decision will be made.

The Bottom Line

A 41-year-old US Army member assigned to NATO’s Allied Rapid Reaction Corps was arrested near Gloucester on 10 November on suspicion of offences under Sections 1 and 3 of the National Security Act 2023, with the allegations relating to Russia, according to the Metropolitan Police and ARRC. He remains in custody in London while Counter Terrorism Policing, the FBI and US Army counterintelligence continue the investigation.
