Firefighters got the call just after 9:30 p.m. about heavy smoke and flames that erupted at the building.

Once battling the flames, they discovered the reason it was so difficult to contain.

“They found heavy fire and smoke shooting out of the roof of the building,” said Lt. Kristen Miller with Miami-Dade Fire Rescue. “We went into what we call a defensive attack immediately due to the intensity of the fire. During the course of the firefighting we discovered there was a ruptured gas line which was why it was so difficult to extinguish the fire.”

Once firefighters got that that gas line secured then they quickly started making progress.
