At 00.30, the police were alerted to Sigtuna City Hall in Stockholm County after a firebomb was thrown at Sigtuna City Hall.
A fire broke out outside the town hall.
The rescue service was able to extinguish the fire quickly.
Will the town hall be able to stay open?
- I do not know if it is open.
The municipality knows about this and the staff can probably take a different path than through the entrance, says the police officer on duty Tomas Ibstedt.
Several police officers have been called to the scene and during Monday morning a technical investigation will be carried out.
No person has been physically injured and no suspect has been arrested.
