Six taxis and a factory have been damaged in a suspicious fire at Tullamarine, as police search for witnesses to the blaze.
Emergency services were called to Derby Street about 12.30am on Wednesday after neighbours noticed a taxi on fire.
It was one of six parked on the street, close to a factory wall.
The flames spread to the other five cars, destroying all six taxis and damaging the factory façade, before being brought under control.
No one was injured in the fire.
The fire is being treated as suspicious and a crime scene guard will remain at the site until morning.
Anyone with information about the fire is urged to contact Crime Stoppers on 1800 333 000.
