The man was alleged to have threatened a woman with a knife and claimed to have a bomb
Around 9pm, police were called to the global terminal following reports of a man in the food court, armed with a knife who was threatening a woman who is known to him.
"I think this photo (of the fake bomb) clearly indicate the extraordinary lengths that a person has gone to to create a perception of risk, threat and fear".
