Police investigations of the shooting incident took place on Monday night and into the early hours of Tuesday, lead investigator Kenneth Jensen confirmed on Tuesday morning.
An alert was raised as to the shooting at Toftegårds Plads in Valby just before 10pm on Monday.
Investigation of the scene showed at least one shot was fired, Jensen confirmed.
Shortly after the first alert, police were informed of a possible knife attack at nearby street Gammel Køge Landevej.
In that incident, a 21-year-old male was beaten and kicked by a group of young people.
“We have a strong suspicion that the assault at Gammel Køge Landevej was a follow-on from the incident at Toftegårds Plads,” Jensen said.
A pistol was found close to the victim of the assault, who was taken to hospital but face charges for illegal possession of a firearm, the lead inspector confirmed.
Police were unable on Tuesday morning to make any comment regarding a potential connection to an ongoing conflict between organized crime gangs in Copenhagen.
The most recent incident to be linked to ongoing violence in this regard is the explosion of a suspected hand grenade in Amager on Monday.
The government last week announced a major beefing up of security, including public surveillance and border checks, linked to the recent spate of organized crime-linked violence.
