Clarence Town Preschool has had four hoses stolen in seven weeks.
Three of the hoses were on a hose reel outside the preschool. The fourth was in the shed. Thieves used bolt cutters to break into the shed and steel the hose and a First Aid kit.
The preschool believes its water supply is being used by an external purpose.
Two of the hoses were donated. The preschool cannot operate without a First Aid kit.
Phone police on 4992 3004.
