The incident was initially described as ongoing life-threatening violence and people were urged to stay away. According to Norwegian police, two people got into a fight, whereupon one of them fired several shots with a pistol.
The two are said to have then left the shopping center and a search effort is underway. According to the police, they have some form of relationship with each other.
It seems that there has been a targeted conflict inside the center between two groups, says incident leader Arve Røtterud on site to VG.
The incident leader also states that they have found a family member who they are now talking to to get more information.
The person was not on site during the shooting, but came to the site afterwards.
One person has been shot and injured in connection with the incident and has been taken to hospital by ambulance. The extent of the injuries is unclear.
A witness on site tells VG about the incident.
I heard them arguing, then six shots were fired at a table where several people were sitting. I hid behind some shelves, the witness tells the newspaper.
The police state that they have the situation under control and are interviewing witnesses.
