"There was quite a bit of fire when they arrived and a huge plume of smoke could be seen from several miles away," said Westminster Fire Department Lieutenant Jeromy Hill.

The spokesman said they were fighting the fire from a distance because the walls of the building were showing signs of instability.

Meanwhile, dozens of peopled lined up to watch the firefighters in action.

"You could straight-up see fire falling down off the wall into the ground," Solomon Deshyn told FOX31.

As of Thursday night, firefighters were waiting for the building to cool off, so they could go inside and begin their investigation into what started it.
