The 35-year-old man had barricaded himself and the child in his car at the foot of a Turkish Airlines plane on Saturday evening, demanding to be allowed on board after a custody dispute with the mother.

He had rammed his car through the security area onto the apron where planes are parked, firing two shots in the air and throwing two burning bottles out of the vehicle, police said.

“The hostage-taking has ended,” local police posted on X, formerly Twitter, Sunday afternoon.

“The man has left his car with his daughter and been taken for questioning by security forces without resistance,” it said, adding the child “seems in good health”.

Police had brought psychologists and teams of negotiators as well as rapid response units to the airport in northern Germany. Authorities said a dispute over custody of the child was believed to be behind the incident, with the wife of the driver placing an emergency call alerting police to the abduction of her child.

Police had described lengthy negotiations which had taken place in Turkish and announced the father was believed to be “in possession of a loaded weapon and perhaps explosives”.

The man, a Turk according to the daily Bild newspaper, had at first demanded to be allowed to fly to Turkey with his daughter.

“That’s no longer the aim of negotiations,” a local police spokesperson had said. “We believe that the child is physically well,” police spokeswoman Sandra Levgruen told regional television channel NDR.

“That’s what we can see and what we gather from telephone conversations with the man responsible for what has happened. We can hear the child in the background.”

“I don’t want to talk about her mental state,” the spokeswoman added. “We are talking, talking and talking again,” with the father, and “trying to find a peaceful solution,” she had added.

On Sunday morning the airport management posted on X saying, “Air traffic remains suspended until further notice.”

On Saturday evening, 17 flights scheduled to land in Hamburg were diverted. Another 286 flights were scheduled for Sunday, carrying some 34,500 passengers.
