Danish police say that the gunman who opened fire in a shopping mall in Copenhagen most likely acted alone and selected his victims at random.
Copenhagen chief police inspector Soren Thomassen said on July 4 investigators do not believe the previous day's attack was terror-related.
Thomassen said three people were killed -- two Danes and one Russian citizen -- and two Danes and two Swedes were hospitalized with serious injuries.
A 22-year-old Danish man was arrested after the shooting on July 3 that caused panic at a mall in South Copenhagen. The suspect will face questioning by a judge on July 4.
Danish police said on July 4 that the suspect was known to mental-health services.
"Our suspect is also known among psychiatric services. Beyond that I do not wish to comment," Thomassen told a press conference.
