An investigation has been launched after firefighters spent several hours tackling a blaze at a farm in Crieff.
Crews were called to Broich Road, near Crieff High School, at around 9pm on Monday – where a “large number” of hay bales were alight.
The fire is thought to have been started deliberately.
Sergeant David Patton of Crieff police station said: “Fires such as this cause substantial financial loss to farmers and a number of fire appliances sent several hours working to extinguish it.
