The Federal Police operate two separate services at the airport: the aviation police and the federal judicial police.
The aviation police are responsible among other things for the border control and the general policing of the airport complex. They also man the main call centre. The agents usually wear uniforms.
The federal judicial police at the airport - often in plain clothes - specialise in judicial investigations, mainly in the area of organised cross-border crime.
The police services at the airport are permanently available on the central telephone number: +32 2 709 66 66
