Police investigating the placing of a poster carrying what purported to be the details of serving PSNI officers have made two arrests.
The two men, aged 58 and 38, were detained under terrorism legislation.
Police confirmed she had no historic or current link to the PSNI and said it was "one of a number of inaccuracies contained in the poster".
On 8 August the PSNI inadvertently issued details of its 10,000 serving officers and civilian staff.
The information was in the form of a spreadsheet attached to a published Freedom of Information request.
The detail included the surname, initials, rank/grade, role, service number, department, location, duty type and gender of all serving officers and staff.
The PSNI has confirmed that the information is now in the hands of dissident republicans.
The mistake has contributed to huge pressure on PSNI Chief Constable Simon Byrne to resign.
A senior British police officer has been appointed to conduct a review of the data breach.
It is expected to be concluded by the end of November.
One man has appeared in court charged with possessing information released by the PSNI.
