A US military officer was arrested in Britain on suspicion of spying for Russia. The Kremlin denies any connection with him.
The 41-year-old US Army soldier was arrested on November 10 about 100 miles west of London, near Gloucester.
London police said in a statement that the charges were related to Russia. The military man is suspected of receiving or disclosing secret information and providing assistance to foreign intelligence.
US counterintelligence chief Sean Stinson called the detainee "senior military personnel with access to classified information." His identity has not been revealed.
Police are searching two addresses in Gloucestershire as part of their investigation.
Russian President Vladimir Putin's Press Secretary Dmitry Peskov claims that the Russian side has nothing to do with what happened. "This arrest has nothing to do with us, and we don't know what it has to do with," he said.
