A 31-year-old man is due to appear in court on Thursday after being charged with offences linked to alleged assistance to a Russian intelligence service.
The man has been named as Joshua Cammidge. He is accused of two offences under the National Security Act.
The charges relate to allegations involving a Russian intelligence service, but the available information does not set out the specific conduct said to form the basis of the case.
The next stage in the proceedings is expected to be his court appearance on Thursday, where the charges against him will be formally considered.
