A Werribee barber shop has been targeted in the early hours.
Emergency services were called to reports the Derwent Road business had been rammed and firebombed just after 1.30am Monday.
Two offenders were seen running from the area a short time later.
FRV crews found the single storey shop well alight when they arrived, working to isolate the blaze before it could spread to a nearby shop and home.
The flames were brought under control within an hour.
FRV says residents in the nearby home evacuated safely.
Police are now investigating, and are yet to confirm if its is linked to other shop fires across Melbourne.
Anyone with information or footage is being urged to call Crime Stoppers on 1800 333 000.
