PSNI Data Breach Terrorism Cases
Coverage from The Irish Times, MCAC, and others
The topic concerns terrorism-related prosecutions arising from the Police Service of Northern Ireland’s mistaken 2023 release of sensitive information about more than 10,000 officers and staff under a Freedom of Information request.
Christopher Paul O’Kane was convicted at Belfast Crown Court after prosecutors linked his possession and handling of the data to preparation of terrorist acts, while separate proceedings against Brian Francis Cavlan and Rory Martin Logan remain contested. The cases show how an accidental disclosure of police personnel information has continued to generate security, evidentiary, and criminal justice consequences.
The main change is that the reporting now includes O’Kane being remanded in custody pending sentencing, adding a concrete post-conviction procedural step. The separate Cavlan and Logan matters are also framed more explicitly as still unresolved, with their defense challenges highlighted.
The biggest update is that O’Kane’s case has now culminated in a Belfast Crown Court conviction and judge identification, sharpening the story from an ongoing dispute into a completed terrorism verdict tied to the PSNI breach. The current version also adds that the separate Cavlan and Logan matters remain live and spans allegations into 2024, reinforcing that the legal fallout is still unfolding on a case-by-case basis.
