A thick cloud of smoke filled the sky as firefighters tackled a huge tyres blaze at a disused factory.
The fire raged through the building in Trowell on the Nottngham-Derbyshire border after around 3,000 tyres caught light.
An investigation has been launched after fire broke out at the former factory on Ilkeston Road and the building was badly damaged on Friday night.
Derbyshire fire spokesman Simon Fairchild said the tyres were allowed to burn out naturally to stop pollution in the River Erewash from run-off.
He said: “There were about 3,000 tyres stored in the basement and we were informed by the Environment Agency that we should not use water but just control the incident.
“The environmental impact of water run-off from the fire in the local area would have been disastrous.”
The three-storey building was badly damaged and will be demolished as soon as possible, the fire service said.
