A soldier in the US Army has been arrested on suspicion of spying for Russia, British counter-terror police have said.
The 41-year-old senior serviceman was arrested near Gloucester on Tuesday.
Counter Terrorism Policing London said the man had been arrested under section one and section three of the National Security Act 2023.
Section one of the Act relates to obtaining or disclosing protected information, while section three relates to assisting a foreign intelligence service.
As part of the investigation, officers are carrying out searches at two locations in Gloucestershire.
The BBC understands the soldier was based at Imjin Barracks in Innsworth, Gloucestershire. The barracks serve as the headquarters of Nato’s Allied Rapid Reaction Corps (ARRC), a strategic operational base for the alliance.
Counter Terrorism Policing said it was not linked to any other ongoing investigations.
FBI director Kash Patel said in a statement: “This important arrest involves allegations of espionage, which is of the utmost concern to the United States and our allies.”
He added: “While this investigation is continuing, I want to send a clear message – 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.”
Deputy Assistant Commissioner Vicki Evans, from Counter Terrorism Policing London, described the arrest as “significant”.
