Newcastle Citizen's Advice Bureau data breach concern
An investigation is under way after the Citizen's Advice Bureau in Newcastle inadvertently released personal information about some of its clients.
About 1,300 files containing names, addresses, debt history and criminal records were accidentally made available on the internet.
The Information Commissioner's Office (ICO) is looking into the incident and a possible data protection breach.
Newcastle CAB said all those affected were being contacted.
Shona Alexander, chief executive of the branch, said: "This isolated incident at Newcastle CAB is being thoroughly investigated.
"I'd like to reassure people that, because we take data protection extremely seriously, they can speak to us in total confidence. All Newcastle CAB staff and volunteers are fully trained in information assurance.
"The ICO are aware of this incident and we are working with them, as well as the senior information risk owner at Citizens Advice, taking urgent action to contact anyone who may have been affected by this incident and fully resolving any issues."
An ICO spokesperson said: "We have recently been made aware of a possible data breach which may involve the Newcastle Citizens Advice Bureau.
"We will be making inquiries into the circumstances of the alleged breach of the Data Protection Act before deciding what action, if any, needs to be taken."
