Several Dead In Copenhagen Mall Shooting; Suspect Arrested

Organizers called off the Harry Styles concert, which had been scheduled at the nearby Royal Arena, by order of police.

A gunman opened fire inside a busy shopping mall in the Danish capital Sunday, killing several people and wounding several others, police said.

A 22-year-old Danish man was arrested, Copenhagen police inspector Søren Thomassen told reporters, adding there was no indication that anyone else was involved in the attack, though police were still investigating.

Gun violence is relatively rare in Denmark.
