Two fires over the weekend

Suspect sought over Whyalla Stuart fire

One suspect has been arrested while another is being sought by police following two house fires in Whyalla over the long weekend.

Police and fire crews called to a house in Havelberg Street on October 7 after reports that a woman's house had been set alight.

It's believed that the house was unoccupied at the time, and there were no reports of any injuries. Further investigations led police to a nearby property where a man known to the victim was arrested.

A 22-year-old man from Whyalla Stuart will face numerous charges including arson and property damage. He has been refused bail to appear in the Whyalla Magistrates Court on Tuesday.

Meanwhile police are investigating a house fire at Whyalla in the early hours of Monday morning and are looking for a suspect who may have burnt himself while lighting the fire.

Police and fire crews responded to reports of a fire at a maisonette in Pickhaver Street, Whyalla Stuart about 9.30pm on Saturday, October 5.

The house was significantly damaged by fire, but MFS crews were able to prevent the fire from spreading to the adjoining premises. There were no reports of injuries at the scene.

Local crime scene investigators and CIB detectives attended overnight and determined the cause of the fire to be arson.

CCTV showed a man approaching the premises on a bicycle and throwing a Molotov cocktail. The offender appears to have accidentally set his own arm on fire as he flees the scene.

Police urge the suspect to seek medical treatment for his injury, as burns have a high risk of infection and scarring.

Anyone who saw or heard any suspicious activity in the street or knows anyone who has sustained a similar burn or injury to the arm is asked to contact Crime Stoppers on 1800 333 000 or online at www.crimestopperssa.com.au.
