From BBC:
The Information Commissioner’s office says it has been informed about the serious data protection breach involving a helpline charity in Derry.
Contact NI, which runs the Lifeline service, confirmed the identities of up to 20 people who contacted the service were clearly visible on some of the confidential documents that were found in the city centre at the weekend.
The papers were blown from the sixth floor of the Embassy building in Waterloo Place.
One of the documents, seen by the BBC, appears to identify callers by their first and second names, while others contain personal accounts of counselling conversations.
