Detective Sergeant Jason von Tunk, from the Portland crime investigation unit said police and CFA were called to a grass fire in a vacant block at Portland’s Kennedy Street about 2pm.

“A wire fence and about 20 by ten metres of grassland was burnt,” he said. 

“CFA were quickly on scene and extinguished the fire, preventing any further damage or injuries.

“A witness came forward at the scene and stated he saw a flare being deployed. That is being investigated and we are appealing for anyone with information to come forward.” 

Detective Sergeant von Tunk said the incident was a timely reminder for people to be fire ready. 

“We don’t want incidents where flares are being stolen and fires created,” he said. 

“Flares are highly flammable and can get up to between 1000 and 2000 degrees when ignited.

“We’ve had incidents in the past where flares have created fires, causing significant damage. We don’t want to see that again this summer.” 

Anyone with information is urged to call Portland police or Crime Stoppers on 1800 333 000.
