City fire crews responding to a fire at First Stop Auto on the corner of Adelaide and Metcalf Street last night.
District fire chief Gerry Morris says flames were coming from the back of the building when crews arrived on scene just after 12:30 in the morning.
He says the fire was being fed by discarded car tires that were piled at the back of the building and then it entered the building through the roof.
Crews were on scene for 2 and a half hours.
Morris says the building did sustain damage but should be open for business on Monday.
He says the cause of the fire is suspicious at this time.
