British police say a member of the Royal Navy has been arrested and charged with working for an unnamed foreign power following an investigation by counter-terrorism officers.
The charged man is Teddy Young, 24, who faces two counts under the National Security Act over allegations of collecting protected information and preparing to hand it to a foreign power.
In a statement, authorities alleged that between November 2024 and May 2025 Young "collected, copied, recorded or retained protected information, with the intention that this conduct would benefit a foreign power… contrary to Section 1 of the National Security Act 2023."
Young is expected to appear at Westminster Magistrates' Court in London later on Thursday.
"These are very serious charges against a serving member of the armed forces," Commander Helen Flanagan, head of London's Counter Terrorism Command, said in a statement.
"We have worked very closely with our operational colleagues in the Ministry of Defence throughout the investigation to ensure that appropriate measures could be put in place to mitigate any potential risks in relation to this matter," she added.
British media reported that the serviceman was arrested at his home in Bedfordshire on Tuesday before being taken into custody in London.
Police made clear that the case is not connected to an ongoing investigation into an incident at RAF Fairford.
