Singer Harry Styles said he was "heartbroken" and "devastated" after his concert in Copenhagen was cancelled following a fatal shooting at a shopping centre.
Three people were killed and four others seriously hurt after the incident on Sunday. A 22-year-old Danish man was arrested, a Copenhagen police inspector told reporters, adding there was no indication that anyone else was involved in the attack, though officers were still investigating.
He later said the gunman most likely acted alone and selected his victims at random. Investigators do not believe the attack was terror-related.
