Our firefighters have fought very hard over the last 24 hours to try to contain a fire that threatened homes in Marbelup, just west of Albany.
Around 6pm last night, residents in the area were told to evacuate and find a safer place with emergency warnings put in place by the Department of Fire and Emergency Services (DFES).
They have since been able to contain and control the fire with firies strengthening containment lines.
However, authorities are now on the search for the person or persons who they believe deliberately lit the fire.
If you have any information that can help in the investigation, please call Crime Stoppers on 1800 333 000.
