When the police got to the scene, they were able to confirm that it was gunfire that was heard.
No one has yet been found injured and no one has been arrested for the crime.
The place is now cordoned off and the police have started a preliminary investigation into attempted murder, the police write on their website.
- There were a lot of people in motion at the scene when we arrived.
Much of our job now is about gathering as much testimony as possible.
If you have been at the scene and have any information, you are welcome to contact us and it is good to do so as soon as possible, says police spokesperson Tommy Thorngren.
