POLICE have launched a public appeal to help progress their investigation into a Lake Macquarie fire they suspect may have been lit deliberately on Thursday night.
Fire crews were called to a small grass fire at the intersection of Rutleys Road and the Pacific Highway at Doyalson about 8.30pm on Thursday.
"Once the fire was extinguished, a bottle with a wick implement protruding from it was located nearby," police said in a statement.
Tuggerah Lakes officers have begun making inquiries and are appealing for public help.
They are seeking dash-cam footage from anyone who was driving through the area around the time of the fire, and are specifically seeking a small blue sedan reported to be headed north toward Newcastle on the Pacific Highway at the time.
Thursday was a busy evening for firefighters in Lake Macquarie. At about 7pm, the NSW Rural Fire Service declared a fire burning at Belmont had reached emergency level and was threatening houses.
Anyone with information on the Doyalson incident is urged to call Crime Stoppers on 1800 333 000.
