Glenview Nursery in Tullibody was deliberately set on fire between the evening of Friday 14th April and the afternoon of Saturday 15th April.
A criminal enquiry has been launched after the nursery’s garden was set alight, with flames seen billowing out across the town.
Extensive damage was caused, including the destruction of a children’s playhouse and other outdoor equipment.
The fire then “took effect” on a nearby property, as well as some of the trees in the area.
Sergeant Donald Konkol, from Alloa Police Station, said: “This was a reckless act which has caused damage to the grounds and a neighbouring premises.
“It has meant that children who attend the nursery will lose the use of the facilities, and it is something which affects those in the community who make use of it.
“We would ask anyone who saw suspicious behaviour in the area around this time or has any other information which may be able to help with our enquiries is asked to get in touch as soon as possible.”
