Three teenage boys have been arrested on suspicion of arson following a barn blaze in Dronfield Woodhouse.
Two of the boys, both aged 14, are from Dronfield and the third, also 14, is from Sheffield.
They were arrested after a barn in Rod Moor Road went up in flames at around 5.30pm yesterday.
The two boys from Dronfield were questioned and released on police bail, while the third remains in police custody and will be questioned today.
The barn and its contents were destroyed in the fire.
Hay and farm machinery, worth thousands of pounds, had been stored inside.
Anyone with information should call DC Paula Hoggard or DC Katherine Hewitt at Derbyshire Police on 101.
