Copenhagen, Denmark: A person opened fire on Tuesday inside a court building in the Danish capital, Copenhagen, authorities said. One man was killed and another was seriously wounded.

Police said a suspect was arrested nearby and a shotgun was seized. There was no immediate information on the victims or the suspect.

Soeren Axelsen, the head of the Copenhagen City Court, said it likely was some kind of “a family showdown.”

The shooting happened just before 10am at the Bailiff’s court, which is part of the larger Copenhagen City Court, and is located behind the city hall. Several streets in downtown Copenhagen were cordoned off by police.

Shootings in Danish courts are rare, Axelsen said.
