US Army Soldier Arrested in UK on Suspicion of Espionage Related to Russia
A U.S. Army soldier has been arrested in England on suspicion of espionage related to Russia, British counterterrorism police said. The 41-year-old man, described by Army officials as a "senior soldier," was taken into custody Tuesday, Nov. 10, near Gloucester in western England.
Authorities have not released his name, rank or unit, and he has not been charged.
What Police Say Happened
The soldier was arrested on suspicion of offenses under sections 1 and 3 of the U.K.'s National Security Act 2023. Those sections cover obtaining or disclosing protected information and assisting a foreign intelligence service, Army Times reported.
Police said the allegations relate to Russia but did not share further details. The man was taken to a police station in London, and officers searched two locations in Gloucestershire.
The Metropolitan Police said its counterterrorism officers worked closely with the FBI and the U.S. military on the case. Police also said the arrest "is not linked to any other ongoing Counter Terrorism Policing investigations."
U.S. Officials Respond
FBI Director Kash Patel called it an "important arrest" involving "allegations of espionage" that are of "utmost concern" to the United States and its allies, PBS NewsHour reported.
Brig. Gen. Sean Stinchon, commanding general of the U.S. Army Counterintelligence Command, described the suspect as a "senior soldier" in a news release. He said insider threats are "real and persistent."
The Army's Counterintelligence Command declined to share more information about the case. Officials have not said what kind of information the soldier allegedly obtained or shared, or how long the investigation had been underway.
A Tense Time for U.S. Bases in Britain
The arrest comes during a period of heightened security concerns at U.S. military sites in England. Police stressed that this case is not connected to a suspected Iran-linked terror plot in September at RAF Fairford, a U.S.-run base near Gloucester.
After that threat, the U.S. Air Force withdrew bombers from Fairford. The arrest also came a day after the U.S. moved refueling aircraft out of RAF Mildenhall, a move the Wall Street Journal reported was prompted by an Iran-related threat.
Authorities have not linked the soldier's arrest to either of those developments.
Russia's Spying Campaign in Europe
British officials have warned about what they describe as an increasingly bold Russian campaign of espionage, sabotage and cyber interference.
Since Russia's invasion of Ukraine, the Associated Press has tracked around 200 incidents of sabotage and other hostile activity across Europe that Western officials have blamed on Moscow. Those include plots to set fire to warehouses, drone launches, attempted killings, theft of defense technology and cyberattacks on critical infrastructure. In August, an attempted drone attack on a German airport led Germany to shut down a Russian consulate.
In October 2025, London police arrested three men on suspicion of assisting a foreign intelligence service under the same law, in a case the AP reported was linked to Russia. At the time, counterterrorism officials said they were seeing more "proxies" recruited by foreign intelligence agencies, Al Jazeera reported.
Britain has also prosecuted Russia-linked plots. Six men were sentenced for an arson attack on Ukraine-linked businesses in east London that prosecutors said was ordered by Russia's Wagner group. The ringleader, Dylan Earl, became the first person convicted under the National Security Act.
In October 2025, the head of Britain's MI5 security service, Ken McCallum, said that Russia "is committed to causing havoc and destruction."
The Kremlin has repeatedly denied involvement in sabotage, saying the British government blames Russia for anything negative that happens in the U.K.
The investigation into the soldier is ongoing, and he has not been convicted of any crime.
