Arson Squad detectives are continuing their investigations into a house fire in Port Kennedy a month ago that left a woman with serious burns.
A 58-year-old man has already been charged with attempting to unlawfully kill and criminal damage by fire after allegedly setting fire to the home on Endeavour Drive on Monday, August 31.
Detectives are now trying to establish a timeline of events and have released an image of a person who they are asking the public to help identify.
They believe this person, who may have been carrying two jerry cans, travelled between Rockingham and Port Kennedy between 3pm and 10pm on the day of the fire.
Detectives urge anyone who recognises the person pictured, or who has any information relating to this incident, to contact Crime Stoppers online at www.crimestopperswa.com.au or by calling 1800 333 000.
Information can be reported anonymously.
