A second man has been arrested amid an investigation into a leak of PSNI data.
Last week, the personal details of 10,000 PSNI officers and staff were shared on the internet by an employee responding to a Freedom of Information request.
Today, a 50-year-old man was arrested under the Terrorism Act in Derry following a search.

On Tuesday, the PSNI arrested a man, aged 39, who was later released.
The force is working to establish who is in possession of the information leaked during the data leak.
"We will take action to ensure that any criminality identified is dealt with robustly to keep communities, and our officers and staff who serve them, safe," Detective Chief Superintendent Andy Hill said.
