It was at a quarter to five that the alarm came.
Police, ambulance and rescue services were sent to the scene.
- It turned out that something has detonated.
We have cordoned off the site and will conduct a technical investigation, says Per Fahlstöm, spokesperson for the police.
The explosion took place in the immediate vicinity of a home, but no person was injured, according to the police.
It is currently unclear how large the material damage is.
If there is a threat against anyone in the area, the police do not want to comment, nor if there may be a connection to explosions in nearby Farsta earlier this week.
A preliminary investigation into serious illegal threats and public destruction has been launched.
