There is damage to the gate and window panes, says RLC commander Daniel Ågren.
There is no information about personal injuries. The national bomb squad has been called to the scene and a police helicopter is circling the area.
We have accommodated the residents, we want them to stay there until the bomb squad has investigated so that there are no undetonated explosive charges, says Daniel Ågren.
The incident is being investigated as reckless endangerment and serious offense against the law on fire hazardous and explosive goods. Currently, there is no suspected perpetrator.
