British police have arrested a senior member of the United States Army in England on suspicion of assisting Russian intelligence, in the first known case of its kind under Britain's National Security Act. The 41-year-old man was arrested near the city of Gloucester on Tuesday by officers from Counter Terrorism Policing, working closely with American authorities, the FBI and the US military.
The Metropolitan Police said the soldier, whose identity has not been released, was arrested on suspicion of offences under sections 1 and 3 of the National Security Act 2023. Section 1 concerns obtaining or disclosing protected information, and section 3 concerns assisting a foreign intelligence service. Police confirmed that the country to which the allegations relate is Russia. The man remains in custody at a London police station, and officers are carrying out searches at two locations in Gloucestershire.
A senior NATO official told CNN that the soldier was assigned to the Allied Rapid Reaction Corps, the British-led NATO corps headquartered at Imjin Barracks in Innsworth, near Gloucester. The corps is tasked with rapid deployment in response to crises across Europe, and the posting would have given the soldier access to sensitive material about the alliance's plans and capabilities.
Brigadier General Sean Stinchon, the commanding general of the US Army Counterintelligence Command, said in the police statement that the "senior soldier" in question had been "entrusted with sensitive information". FBI Director Kash Patel said the arrest "involves allegations of espionage, which is of the utmost concern to the United States and our allies". The US Army Counter-Intelligence Command declined to comment further when approached by American media.
The National Security Act 2023 was introduced in response to rising threats from state-sponsored espionage, and it gives the authorities powers to detain suspects for up to 14 days without charge. The legislation was designed to deal with exactly this kind of case: a serving member of an allied military accused of passing protected information to a hostile foreign intelligence service. Legal experts say the case will test the new law in a high-profile setting, and that any prosecution is likely to be closely watched in London, Washington and Moscow alike.
The Metropolitan Police stressed that the arrest is "not linked to any other ongoing Counter Terrorism Policing investigations", a point the force made twice in its statement, apparently to head off speculation that the case is connected to the separate terror investigation around RAF Fairford. That case, in which American prosecutors on Tuesday charged three Iran-backed men over a foiled plot against the Gloucestershire airbase, is a separate matter, although both have raised questions in the same week about the security of American forces stationed in Britain.
The arrest comes only days after the United States removed its bombers from British military bases over the apparent threat from Iran, and it adds to a growing sense in London that Britain has become a front line in the intelligence contest between Russia and the West. Gloucester is also home to the Government Communications Headquarters, Britain's signals intelligence agency, and the region hosts a cluster of military and intelligence facilities that make it a natural target for foreign intelligence services.
For the British government, the case is awkward as well as serious. The soldier was a guest in the country, serving alongside British troops in a NATO headquarters, and the allegations, if proved, would amount to a betrayal of the trust placed in him by both nations. Ministers have so far said little in public, leaving the Metropolitan Police and the FBI to lead the response, but the case is certain to be raised in Parliament and in the coming days in Washington.
No charges have yet been brought, and under British law the soldier is entitled to the presumption of innocence. Investigators will now examine the material seized from the two Gloucestershire addresses and decide whether there is enough evidence to bring a case. If charged and convicted under the National Security Act, the soldier could face a lengthy prison sentence, and the case would mark the first time a member of the US armed forces has been prosecuted in Britain for spying for Russia.
The arrest is also a reminder of how far the intelligence war between Russia and the West has escalated since the full-scale invasion of Ukraine. European security services have reported a sharp rise in Russian espionage activity, sabotage and attempted assassinations, and Western governments have expelled hundreds of Russian diplomats and intelligence officers. The detention of an American soldier in England suggests that Moscow's efforts to recruit insiders have not stopped — and that the counter-intelligence response is now reaching into the heart of NATO's own headquarters.
