A woman has been charged with collecting information likely to be useful to terrorists and misconduct in public office.
The 32-year-old is an employee of the NI Housing Executive and was arrested in Belfast on Monday.
The charges relate to information obtained by the woman during the course of her employment in an attempt to identify people who are currently under the PSNI’s witness protection scheme.
She is due to appear at Laganside Magistrates’ Court on Thursday, July 31, 2014.
A 28-year-old woman who was also arrested on Monday was released on Tuesday pending further enquiries.
A PSNI spokesman said: “The Police Service of Northern Ireland takes its witness protection obligations extremely seriously and continually reviews measures to keep individuals safe.
“Under the terms of the Serious Organised Crime and Police Act 2005, it is an offence to disclose the identities of individuals subject to protection arrangements. As such, police will not be doing so in this case.”
The charges will be reviewed by the Public Prosecution Service.
