Four cars were damaged after a suspected arson attack in Eckington.
The emergency services were called to an address on High Street at around 1am yesterday after reports that four cars parked on the same drive were on fire.
A Derbyshire Police spokeswoman said the fire was started in a Mini Cooper and spread to a Ford Fiesta, a Ford Ka and a Toyota Rav 4.
Firefighters put out the blaze and no one was injured.
A joint investigation by Derbyshire police and Derbyshire fire service is under way.
A police spokeswoman said: “Officers are keen to speak to anyone who saw any suspicious activity in the area around the time of the fire or if someone they know has any unexplained burns or scorch marks on their body or clothes.
“Police would also like to speak to anyone who saw a dark car, possibly a Ford Focus, in the area around the time of the fire.”
Officers are investigating a link between that car and a Ford Focus found abandoned at the junction of Birley Lane and Birley Moor Road in Owlthorpe, Sheffield.
The abandoned car had been stolen from a house in Eckington earlier in the night.
n Anyone with information is asked to call Derbyshire Police CID on 101.
