Northern Ireland's Police Ombudsman has apologised over a data leak that included the details of 160 staff.
The ombudsman said the data breach occurred on 29 August and that they became aware of it the following day.
The information in the breach contained details of the workforce in May 2022.
It has appointed an external investigator to review the incident and make recommendations.
A three-page word document containing the forename initial and surname of staff members was inadvertently released to 22 people.
The individuals had been invited to a job interview.
It was attached to an email they were sent.
The list also contained details of staff who had resigned, were due to retire, were on career breaks or were about to take up jobs with the ombudsman's office.
Some forenames were included in this information.
In a statement, the organisation said no other personal information was contained in the document.
Action was taken to mitigate the data breach, including contacting the 22 people who received the information in error.
So far, 20 of the 22 have confirmed that they have deleted the information.
"We have apologised unreservedly to our current staff for the error which should not have happened and are also contacting former staff whose details are included in the document," the ombudsman's office said.
"In total 160 current and former staff are affected," it added.
The Information Commissioner's Office has been alerted to the leak.
