3 killed, 4 critically wounded in shooting at Copenhagen shopping mall, police say

LONDON -- At least three people were killed and seven others were critically wounded in a shooting at a Copenhagen shopping mall on Sunday, authorities said.

Police responded to reports of a shooting at the Field's shopping center in Denmark's capital just before 5:30 p.m. local time on Sunday. A boy and a girl, both 17-year-old Danish citizens, and a 47-year-old Russian man were killed when a gunman opened fire there, according to Copenhagen chief police inspector Søren Thomassen.

Four people -- a Swedish 16-year-old girl, a Danish 19-year-old woman, a 40-year-old Danish woman, and a 50-year-old Swedish man -- were "seriously injured," according to police.

Three others, a 15-year-old Danish girl, a 17-year-old Danish girl, and a 45-year-old Afghan citizen who lives in Denmark, were "slightly injured," police said.

Several others suffered minor injuries while fleeing the mall, Thomassen said.

The suspect -- a 22-year-old man with a history of mental health issues -- was arrested at the scene, according to Thomassen. He was expected to be arraigned in a Danish court on Monday on preliminary charges of murder.

He is being held at at a closed psychiatric ward, said authorities, who did not know the gunman's motive for the shooting.

Thomassen said the victims appeared to have been randomly targeted and the gunman was believed to have acted alone. There was also nothing to suggest terrorism, he said.

"There is nothing in our investigation, or the documents we have reviewed, or the things we have found, or the witnesses' statements we have gotten, that can substantiate that this is an act of terrorism," the police inspector told reporters during a press conference Monday.

The deadly shooting remains under investigation.
