A senior US Army serviceman has been arrested in Britain on suspicion of offenses under the National Security Act with an alleged connection to Russia. Radio Free Europe/Radio Liberty reported the case on Tuesday, November 10.

The 41-year-old was detained near Gloucester. Investigators are examining suspected acquisition or disclosure of protected information and possible assistance to a foreign intelligence service, while searches are being carried out at two properties in Gloucestershire.

The BBC said the serviceman was assigned to Imjin Barracks in Innsworth, the site of NATO’s Allied Rapid Reaction Corps headquarters. London’s Metropolitan Police said British investigators had worked closely with US authorities, including the FBI.

FBI Director Kash Patel described the arrest as an important action related to espionage allegations and said the bureau would not tolerate conduct endangering US or partner security. The suspect has not been named and remains in custody at a London police station.
