At 12.53, the police received an alarm about smoke in a school in central Trollhättan.

Emergency services and an ambulance were called to the scene, but it is currently unclear if anyone needed care.

According to Fredrik Svedemyr, someone must have placed something that generated in a smoke that caused some breathing problems and coughing.

- There are some students and a teacher who have experienced problems, but I currently have no information that anyone needed to seek care.

The police have drawn up a report of abuse and at present there are no suspects.

The police do not currently have exact information about the exact circumstances of the incident.

The rescue service has aired out of the premises and students and staff must now have been allowed to enter the school again.
