Police say the incident is not connected to ongoing investigations at the RAF Fairford airbase.

Police in the United Kingdom say they have arrested and charged a member of the Royal Navy accused of working with an unnamed foreign power after an investigation by counterterrorism police.

Teddy Young, 24, was charged with two offences under the National Security Act for allegedly obtaining protected information and preparing to transfer it for the benefit of a foreign power.

In a statement, authorities alleged that between November 2024 and May 2025, Young “obtained, copied, recorded or retained protected information, intending the conduct to benefit a foreign power… contrary to section 1 of the National Security Act 2023″.

Young is due to appear at London’s Westminster Magistrates’ Court later on Thursday.

“These are very serious charges against a serving member of the armed forces,” Commander Helen Flanagan, Head of Counter Terrorism Policing London, said in a statement.

“We have worked extremely closely with relevant operational colleagues within the Ministry of Defence as our investigation has progressed to ensure appropriate measures could be taken to mitigate any potential risks linked to this matter,” she added.

UK media reported that the officer was arrested at his home in Bedfordshire on Tuesday before he was taken into custody in London.

The police clarified that the case is not related to the ongoing investigation into an incident at the RAF Fairford airbase.
