A car fire caused thick plumes of black smoke to billow over Belper town centre.
Firefighters were called to private car park on Campbell Street at around 1.28pm on Thursday, July 3.
The blaze spread to another saloon car and several small explosions were heard by onlookers.
Police closed the road until around 2.48pm, while crews dealt with the fire.
Witness, Christina Powell, said: “Both cars were pluming thick black smoke onto the streets surrounding before the fire brigade arrived.
“The men from the local garage had tried to jack the car out of the way but were unsuccessful in both moving it and putting out the fire with extinguishers.
“The fire brigade arrived and contained the fire to the two cars although a third car was damaged by the heat. There were several loud bangs as we watched the fire get worse.
“When the fire brigade arrived they were concerned for the adjacent building formerly the Buildbase site.”
A spokesman for Derbyshire Fire & Rescue Service said they received a call from one person concerned the blaze might spread to nearby properties.
The fire was out by 2.12pm, when firefighters left the scene.
They used breathing equipment and two hoses to extinguish the blaze.
