The incident took place in an airport parking lot, police said. An injured person has been taken to hospital. The victim was not seriously injured and was treated as an outpatient at a nearby hospital.
A spokeswoman for the federal police said the wanted man is wanted jointly by federal and state police.
She added security camera footage showing two men walking toward an airport parking lot at 6 p.m. 12.16 local time at what time the attack took place.
Andre Hartwich, a spokesman for Düsseldorf police, said the attack took place on a parking meter in one of the airport’s car parks.
He added that there was likely to be a dispute over territorial claims among the homeless.
Sir. Hartwich said: “The names of both people are known to us.”
The spokesman added neither flight safety nor passengers.
Düsseldorf is the third largest airport in Germany behind those located in Frankfurt and Munich.
In 2019, the airport handled 25.5 million passengers.
It is the main hub for Eurowings and a major city for several other airlines.
Düsseldorf Airport has three passenger terminals and two runways that can handle wide planes up to the Airbus A380.
