A 45-year-old man of Ukrainian origin who also holds Irish citizenship has been kept in custody after being accused of passing sensitive Irish Government material to contacts linked to a foreign intelligence agency. The allegations concern a civil servant, placing the case at the center of a serious security and political investigation.

The man was arrested in the departures area of Dublin Airport. Court details indicated he was carrying €5,650 and a one-way ticket when he was stopped, facts that formed part of the background to the latest hearing.

The court further remanded him in custody while waiting for directions from prosecutors on how the case should proceed. That means he will remain detained for now as the legal process moves forward and authorities consider the next procedural steps.

The accusations relate to confidential Government information, but they have not been tested at trial. At this stage, the latest court decision deals with custody and case management rather than any finding on guilt or innocence.
