Police remain tight-lipped on whether they have made progress in finding the person responsible for a bomb scare at Queenstown Airport yesterday.
The airport activated its emergency security protocols after a note mentioning a bomb was found by a cleaner on a Qantas flight from Sydney after it landed at 2.14pm.
Senior Sergeant Paula Enoka, of Queenstown, said the investigation was continuing and witnesses spoken to so far had been cooperative.
She would not comment on the note's wording or other features, and said police would only make the note public if it was useful to the investigation to do so.
