Qantas chief executive Alan Joyce was speaking at a business breakfast in Perth, when a man walked up and shoved a pie in his face. The man who was wearing a business suit and appeared to be in his sixties has been detained. Joyce said to the 500 plus audience, "I don't know what that was about."

He then left the stage to clean his face before returning to a round of applause.

"Now, if there are any more pies can you get it over with now," he joked on his return.

Joyce made light of the incident and said he did not know what type of pie had been used.

"I didn't have a chance to test it — it was mostly on my glasses," he said.

He said it was the first time a pie had been thrown at him.

"Well I think when you've been CEO of an airline for nine years there's a lot of things that happen over that period of time," he said.

"This is different ... it is an unusual event but these things happen."

Joyce said it was important to let police investigate the incident.

According to the BBC, Joyce had been discussing the airline's recent decision to operate non-stop flights from London to Perth.

A Western Australia Police spokesman said it was currently investigating the incident and interviewing the individual concerned
