Three boys have been arrested following a fire at a supermarket filling station in Nottinghamshire.
Emergency crews were called to Asda in Radford Road, Hyson Green, just before 1900 GMT on Sunday.
Two 12-year-old boys and one 13-year-old boy were arrested on suspicion of arson with intent to endanger life.
The 13-year-old suffered minor burns and was taken to the Queen's Medical Centre for treatment where he remained overnight.
It is thought the fire started after plastic fuel pipe covers were set alight, police said.
