Officials at the operator of Fukuoka Airport in western Japan have mistakenly sent the entry passcodes for some doors in the airport building to media outlets.
They say they planned to send the codes by fax to shops and companies in the airport terminal on Monday evening. That was as part of measures to step up security ahead of a meeting of G20 finance ministers and central bank governors in Fukuoka City next month.
But airport staff failed to check the destinations of the fax and local media outlets instead received codes to enter 10 doors connected to shops' storage areas. A map of the areas was also included.
The airport officials say the doors are not connected to restricted areas and that they have already changed the passcodes.
