Shocking CCTV footage appears to show three teenage girls lighting a grass fire in Melton West earlier this month.

Investigators are hunting for the trio who lit the fire under the Roslyn Park Drive overpass about 8.50pm on January 3.

The footage shows the girls leaning over a concrete barrier into the long grass. They begin to run, but pause briefly and then flee the scene once the grass erupts into flames.

No one was injured and no property damaged as a result of the fire, and
the maximum temperature was only
22 degrees on that day in Melton,
however the fire spread rapidly along the creek before being extinguished by fire crews.

The trio was last seen running away from the fire along the bike path near the creek.

Anyone who recognises the youths depicted above or who may have other useful information is urged to contact Crime Stoppers on 1800 333 000.
