Denmark shooting: Harry Styles cancels Copenhagen concert in the wake of deadly attack that left three dead

British singer Harry Styles is "heartbroken" and "devastated" after a deadly shooting was carried out at a shopping mall in Copenhagen, Denmark on Sunday (local time). 

The 'Sign of the Times' and 'Watermelon Sugar' singer, formerly a member of the boy band One Direction, had been due to perform at Copenhagen's Royal Arena on Sunday as part of his tour, 'Love On Tour', but decided to cancel the concert in the wake of the shooting.

Three people were killed and several others wounded in the shooting at Field's mall in the capital, Danish police said. A 22-year-old Danish man has been arrested and charged with manslaughter. 

"I'm heartbroken along with the people of Copenhagen. I adore this city. The people are so warm and full of love. I'm devastated for the victims, their families, and everyone hurting," Styles wrote on Twitter.

"I'm sorry we couldn't be together. Please look after each other."

Chief Police Inspector Soren Thomassen told reporters on Monday (local time) there was no indication the shooting had been an "act of terror" or that the suspect had acted with others.

Thomassen confirmed the shooter killed two 17-year-olds - a man and a woman - and a 47-year-old Russian citizen living in Denmark.
