A man is facing charges of arson and risking a catastrophe after police say he allegedly tried to start a fire inside a Giant Eagle Market District in Aspinwall.

Pittsburgh police say 33-year-old Russell Welenski took a seat in the café area Wednesday night and lit a fire, then walked out, allegedly holding a grill lighter.

The store was evacuated as smoke began to fill the building. As the small fire grew, police said a store employee jumped into action with a fire extinguisher, braving the smoke to put out the flames.

"Hero. Most of the people would run, you know?" said shopper Vaclav David.

On Friday, soot marks could still be seen on the ceiling near where the fire broke out.
