CONCERNING: Police and fire authorities gather to discuss a deliberately lit fire near Kookora Street on Monday, which is still under investigation.
AUTHORITIES are on the hunt for a suspected arsonist who is believed to be behind a spate of deliberately lit blazes across the city this week.
Since December, emergency services have been called out to dozens of suspicious blazes in parks, bushland and grass areas across Griffith.
The most recent was on Tuesday, when Fire and Rescue NSW crews were called out to a blaze on Kookora Street which burnt half a hectare of grassland.
Just a day earlier, crews were called to a fire on Yarrabee Street which burnt an acre of land along the canal.
Investigations into both blazes are continuing.
Fire and Rescue NSW Inspector Steve Knight said it was a concern and he warned people not to get complacent, despite slightly cooler temperatures.
"The grass has dried out now and the risk is still there," Inspector Knight said.
"Anyone who sees someone lighting fires must immediately contact the police."
On Saturday, the Rural Fire Service (RFS) was called out to a deliberately lit blaze on Rifle Range Road home to scrubby bushland which needs little encouragement to burn.
The speedy response of emergency services meant the fire was quickly brought under control before it could do any major damage, but vital fire and police resources were tied up attending to the area.
RFS community safety officer Matthew Ross said it was often difficult to determine when a fire had been deliberately lit.
"There have been a few in the last couple of months," Inspector Ross said.
"Especially up on the hill compared to a non-populated hill like Cocoparra, which has had none, someone has to be lighting them, they don't just start themselves."
With the weather this weekend predicted to creep into the high 30s, emergency services will be on high alert.
Anyone who comes across a fire should report it immediately, while if anyone sees somebody lighting a fire, they should report it to police.
