Police investigating criminality linked to the PSNI data breach have made an arrest.
The personal details of police officers and civilian staff were mistakenly leaked as part of a Freedom of Information request.
Some of the information was later posted on a wall opposite a Sinn Fein office in West Belfast.
Today, a 50 year old man was arrested in the Dungiven area of Derry under the Northern Ireland Terrorism Act.
He's being questioned by detectives at the Musgrave Serious Crime Suite.
