The security service might be able to find out who accessed the personal and employment details of thousands of Police Service of Northern Ireland (PSNI) officers and civilian staff after they were posted online in a major data breach, cyber security experts said.
PSNI apologised on Tuesday after it emerged that some 10,000 officers and staff were affected by the breach, which happened when it responded to a Freedom of Information request seeking the number of officers and staff at all ranks and grades across the organisation.
