FIREFIGHTERS were busy last night extinguishing three significant fires, sparked in less than three hours of each other.

Fire chief Walter Evans said police received the first call shortly after midnight.

"We got a call that the top section of a two-story complex was engulfed in flames on Gladstone Road.

"While firefighters were still at that blaze, less than an hour later, they got another call that a four-plex in Stapeldon was on fire," he said.

"While there, they got yet another call that a tyre shop in the Fritz Lane area was on fire and a heap of tyres were burning.

"All the fires were extinguished and no one was hurt."

Active investigations are continuing.
