Detectives have released CCTV vision and are appealing for public assistance following a suspicious house fire earlier this year.
About 9.50pm on Wednesday, May 25, emergency services responded to reports of a house fire at Dolomite Road, Cranebrook.
The fire was contained to the front room and was extinguished by Fire and Rescue NSW officers a short time later.
No one was home at the time of the fire and there were no reports of any injuries.
Officers from Nepean Police Area Command established a crime scene which was examined by specialist officers.
