AFP Inspector Peter Brindal said aggressive or abusive behaviour towards airline staff was unacceptable.

"Airline staff perform a crucial task in making the airport run smoothly and shouldn't have to deal with unruly people who think the law doesn't apply to them," Insp Brindal said.

"The AFP works closely with its airline partners and won't hesitate to act if called for assistance."
