Younggsters are being warned about the dangers of starting fires after police and firefighters were called to incidents in the Amber Valley area.
On Sunday, July 14, crews were called to Poundstretcher on High Street, Heanor after a pallet was believed to have been set alight at around 6pm, and spreading to the building.
Crews were later called to Station Road, Langley Mill, at 8pm after two bins had been set on fire behind B&M Bargains.
Both incidents are being treated as suspicious and police are making enquiries, though it is not thought they are all linked.
Community Safety Inspector Russell Dakin said: “Fortunately no one became trapped or injured as a result of these incidents, but with any fire there is always the danger that it could get seriously out of hand and put people’s lives at risk.
“It might seem like harmless fun to play with lighters or matches but it’s actually far from it. Small fires can spread rapidly, especially during periods of warm, dry weather, putting people, including the person lighting it, in extreme danger.”
“I would encourage young people to think about the consequences and for parents to educate their children and teenagers about the dangers and risks.
Anyone with information should contact Derbyshire police on 101, or Crimestoppers anonymously on 0800 555 111.
