Police in Fife have arrested two men aged 20 and a 19-year-old man in connection with the ongoing investigation into a deliberate fire in Inverkeithing.
Emergency services responded to the incident at the former Inverkeithing Primary School building on Roods Road on Monday November 19.
Inquiries remain ongoing.
Demolition of the former school has begun amid a campaign to protect the structure.
STOP (Save the Old Primary) Inverkeithing has been set up to try to retain some of the century-old C-listed building.
Fife Council said some demolition was required on grounds of safety but as much would be saved as possible.
