The police cordoned off an area in Møllergata in central Oslo, after a man was said to have been subjected to a serious incident of violence with a sharp object.
The police received the first report of the incident at 20.35. They are now interviewing witnesses at the scene.
The police cordoned off parts of the area shortly after 9 p.m., Avisa Oslo reports. 15 minutes later the restrictions were lifted.
The forensic department is on the scene, the newspaper writes further.
Just before 9.30 pm, the police state that the search for the perpetrator has been completed.
The injured person is said to be a man, says Øyvind Hammervold, operations manager in the Oslo police district.
– He has been sent to hospital and is probably not life-threateningly injured, he tells Nettavisen.
– Can you say something about what kind of object it is?
– We have an idea about it, but as of now we are keeping our options open, so we do not want to go into it, says Hammervold.
The incident must have happened in Møllergata in the center of the capital.
