Once again, a fire totally destroyed a school building at Kvarnby Folk High School (folkhögskola) in Malmö yesterday, reports Swedish Radio's local station.

However while there is evidence that the previous fire, which occurred last October, had been deliberately set, it is unclear what caused yesterday's fire.

This time, it seems that some problem with the electric system caused the fire.

The police say there were no signs of broken windows or that someone got in using violence.
