No injured person has been found.
It is unclear whether the shots were aimed at the door or if someone tried to get to someone on the inside, we do not know that, says Berglund.
The police were alerted at 00.30 and launched a major operation. An investigation into serious weapons offenses and vandalism has been initiated.
We are looking for a perpetrator and are interviewing witnesses on the scene. We are also reviewing security cameras and checking interesting vehicles and individuals, says Niklas Berglund.
