Adelaide teen in hospital with arm burns

Three teenagers have burns following a fire at a sleepout behind a home in Port Pirie, South Australia.

Fire crews were called to the Risdon Park property about 11.45pm on Sunday and took 10 minutes to douse the flames, which caused $30,000 of damage.

One of the boys was taken to hospital with burns to his arm and fire crews say the blaze was accidental.
