A 41-year-old member of the U.S. Army was arrested near Gloucester on Tuesday on suspicion of espionage tied to Russia, British police said, triggering searches of two locations in Gloucestershire and pulling in the FBI and U.S. military as part of the investigation. The soldier has not been publicly named.
The Metropolitan Police said the man was arrested on suspicion of offenses under Sections 1 and 3 of the National Security Act 2023, according to a statement from the Metropolitan Police. Those sections cover allegations including assisting a foreign intelligence service and obtaining or disclosing protected information, and police specified that the country to which the allegations relate is Russia. As of Tuesday, the man remained in custody at a London police station while the investigation continued.
Officers were carrying out searches at two locations in Gloucestershire as part of the inquiry, the Metropolitan Police said, adding that the investigation is being led by officers from CTP London and that enquiries continue. Police also said the case is not linked to any other ongoing Counter Terrorism Policing investigations.
FBI and US Military Drawn Into the Case
Counter Terrorism Policing said it was working closely with U.S. authorities, the U.S. military and the FBI as the investigation unfolds. CNN reported that the unnamed soldier's case has drawn a response from the top of American law enforcement, as detailed by CNN.
FBI Director Kash Patel said in a statement that this FBI has no tolerance for anyone who breaks their oath to the United States and whose actions endanger our national security and that of our partners, per CNN's report. Patel called the arrest important and described the espionage allegations as a matter of utmost concern for the United States and its allies, according to the same account. U.S. federal and military authorities are also involved in the investigation.
Part of a Broader Pattern of Russia-Linked Cases
The arrest echoes a case from October 2025, when three men ages 44, 45 and 48 were arrested in west and central London on suspicion of assisting a Russian intelligence service, as reported by The Guardian. Those men were also held under Section 3 of the National Security Act, with searches continuing at their arrest addresses and another west London location, according to The Guardian. Metropolitan Police Commander Dominic Murphy said at the time that officers were seeing an increasing number of what they would describe as proxies being recruited by foreign intelligence services, per the same report.
On the U.S. side, the Army has also been grappling with a rise in espionage-related cases. Since 2021, Army counterintelligence agents have conducted more than 600 national security investigations, including more than 200 currently open cases, leading to the arrests of at least 25 soldiers and former soldiers suspected of espionage, according to Stars and Stripes. A 2025 Army-wide message directed soldiers and civilian employees to report any offers of secondary employment or requests to join academic projects, citing an uptick in adversary efforts to obtain sensitive information, the publication reported. Army counterintelligence officials said foreign agents have been posing online as consulting firms, corporate recruiters, think tanks and other seemingly legitimate organizations, and personnel were told to report such contacts to an Army counterintelligence special agent within 24 hours. Army intelligence chief Lt. Gen. Tony Hale said in October 2025 that the command's workload had grown every year and was expected to increase again in 2026, per Stars and Stripes.
In a separate case last year, a U.S. Army soldier was arrested for allegedly seeking to pass sensitive information about American battle tanks to the Russian government, according to the U.S. Justice Department as reported by Reuters. No charges, court appearance, or findings have been disclosed in the Gloucester case, and the outcome of the Gloucestershire searches has not been made public. The investigation remains active, with British and American authorities continuing to work the case together.
