Firefighters were called out to deal with a spate of cars set alight in arson attacks overnight.
At 2.20am a car was found burning in Mansfield Road, Intake, Sheffield.
It was so badly damaged, firefighters were unable to determine the make or model.
At 12:40am a car was torched in Vikinglea Road, Manor, also in Sheffield, and just before midnight another car was set alight in Sour Lane, Fishlake, Doncaster.
A Citroen Xsara found burning in Kingston Street, Pitsmoor, Sheffield and a Volkswagen Passat found alight in The Crescent, Dunscroft, Doncaster, are both believed to have caught fire accidentally.
Anyone with information on the arson attacks should call South Yorkshire Police on 101.
