The alarm was received at 01.40 on Saturday night, when the residents of the area were awakened by a loud bang with pressure waves that shook the windows.
- What we know at the moment is that there has been a powerful explosion outside a residential building in Trångsund, which has caused damage to the property and the gate to the property.
We have cordoned off the area right now and are waiting for bomb technicians to make the assessment of whether it is safe to work there, says Peter Asp, officer on duty at the Stockholm Police.
At present, the property has not been completely evacuated.
We have taken out those who were in the stairwell, but those who were on the balconies have had to go into the house and wait until we know more, says Peter Asp.
No injuries were found.
