BERLIN — The hostage situation at Hamburg Airport ended Sunday afternoon, around 18 hours after a man drove his vehicle through the gates of the airport with his 4-year-old daughter as a passenger, authorities said. The man was arrested and the girl is safe.

Hamburg police said that man had left the car with his daughter, who didn't appear to be harmed, and he was "arrested by the emergency services without resistance.” Authorities said the man’s ex-wife had previously contacted them about a child abduction.

The airport in the northern German city had been closed to passengers and flights were canceled since Saturday night when the man, who was armed, broke through an airport gate with his vehicle and fired twice into the air with a weapon, according to German news agency dpa. The man drove the vehicle just outside a terminal building and parked it under a plane.

Police said the 35-year-old man, a Turkish citizen, had his daughter inside the car after reportedly taking her by force from the mother in an ongoing custody battle.

A psychologist had been negotiating with the man for several hours. Nobody was injured during the standoff after all passengers had evacuated the airport, police said.
