No one is to be disciplined over a potential security breach at Dundee Airport, it has been confirmed.
Staff complained to management after confidential personnel files were left lying unattended in unsecured parts of the airport in April information that is used to carry out vital security checks.
The files contained sensitive data about staff and some employees feared it could be used to commit identity theft as it included not only the names of staff but also home addresses, National Insurance numbers and even job references from previous employers.
They are also used to obtain security clearance that allows staff to work airside at any British airports.
Staff believed if this information fell into the wrong hands it could be used to gain access to runways.
Highlands and Islands Airports Ltd (HIAL), which has run Dundee airport on behalf of the city council since 2008, suspended several staff while it investigated the incident.
The three members who were suspended were those who raised concerns with airport management not those responsible for keeping the files secure.
However, a spokeswoman for the company said the investigation has now concluded and nobody has faced disciplinary proceedings as a result.
Police were not involved in the investigation.
Earlier this year firefighters at the airport claimed protective equipment they had been given was not suitable for tackling aviation fires.
HIAL said new equipment was to be issued.
