A US soldier was detained in the UK on suspicion of spying for Russia, according to the London Metropolitan Police. The arrest followed a joint operation between UK counterterror units and the FBI, as well as US military intelligence.

The suspect, whose identity has not been disclosed, was apprehended during a routine security check. Authorities stated that the investigation was part of broader efforts to prevent foreign interference. The UK police emphasized the close coordination with US agencies to ensure the operation's success.

This is the second known case of a US military personnel being investigated for potential espionage in Europe this year. Previous reports indicated similar actions in Germany, where a US officer was questioned over alleged ties to Russian intelligence. The UK's national security agency, GCHQ, has been under increased scrutiny following recent revelations about foreign surveillance activities. The current case highlights ongoing concerns about intelligence cooperation between Western nations and the risks of espionage.
