The airport closed for all takeoffs and landings on Saturday evening, and remains closed today.
Police arrived in large numbers last night as a man, 35, drove through a barrier onto the grounds of the airport with a four-year-old child.
The car was parked under a plane, a police spokesperson said.
A police spokesperson posted to X, formerly known as Twitter, on Sunday: “The operation continues.
“Our negotiators are in contact with the person in the car.”
