The Police Service of Northern Ireland (PSNI) has said it is “extremely disappointed” after failing to have a £750,000 fine reduced over last year’s major data breach. It had made representations to the Information Commissioner’s Office (ICO) who first announced the penalty in May.

The data breach occurred when the service responded to a Freedom of Information request seeking the number of officers and staff of all ranks and grades.

The breach, which exposed the personal details of nearly 9,500 officers, could have been prevented with simple procedures.
