The investigation into the fire that broke out at the Butterfly's preschool in Brandkärr last week is slow. The technical investigation has not revealed what caused the fire.

- There is nothing to indicate that there has been any accident, but we still assume that the fire is on fire.

However, you now know where the fire started.

- We have come to the conclusion that it started on a small courtyard between the built-in housing bodies. It is a very sheltered place with no transparency, says Lars Liewenborg.

The police are currently working on conducting interviews with both staff and witnesses who were on the scene in connection with the discovery of the fire.

- We'll see if the hearings can lead us forward, but it's difficult. For our part, there is nothing to work on.
