Fire has caused extensive damage to a motorcycle repair shop at Thornton this morning.
A security guard noticed smoke coming from an industrial unit on Huntingdale Drive at about 4 o'clock.
Firefighters wearing breathing apparatus cut their way through the front roller door of the Jason's Garage business to find a fire had broken out in the front office.
They've managed to stop the fire spreading to adjoining units.
It's taken just over an hour to douse the flames.
Police are treating the fire as suspicious.
