Firefighters battled a large blaze in Derbyshire.
Crews from Chesterfield, Alfreton, Ilkeston, Ashfield and Eastwood were called to a building at Pye Bridge Industrial Estate, Somercotes, at around 10am today.
Derbyshire fire service said the industrial unit was 'well alight' and several cars were ablaze inside the building.
The blaze is understood to have caused thousands of pounds worth of damage.
There were no reports of any injuries.
A Derbyshire fire service spokesman said: “The most probable cause is being attributed to accidental ignition through works.”
Derbyshire Constabulary advised people in Somercotes to keep doors and windows closed due to the incident and to stay away from the industrial estate and its surrounding area.
Many traders working nearby said they had lost work as they had been forced to shut up shop and send staff home.
