Police Scotland has confirmed that the fire which swept through part of Cairneyhill Primary School on Friday was not started deliberately.
Following a joint investigation with the Scottish Fire and Rescue Service, the force said that the blaze, which started in the infant section of the school at around 1pm, has been established to be “non-suspicious”.
Up to 200 children had to be evacuated from the school to a nearby church hall after the alarm was raised.
A spokesperson for Police Scotland said: “Officers would again like to thank the local community for their cooperation as emergency services responded to the fire.
“We are also reminding people of the dangers of entering premises which have been extensively damaged by fire.
“The building is not structurally stable and has been secured.
“However, we’d urge parents to reinforce the risks of this to their children and ask local residents to be vigilant and report any concerns or signs of entry to us.”
