A man has been arrested after allegedly starting a fire inside a Walmart in Arizona on Thursday, causing at least $6 million in damage.
At around 12:40 p.m. Mesa police and fire officials responded to a 1st Alarm fire call at the Walmart in Mesa.
Mesa police say a transient man started the fire in the Garden Center and upon entry, officials described the smoke as "being so heavy that encompassed their feet, and so thick that the firefighters had little to no visibility as they walked inside."
Firefighters from Mesa, Tempe and the Phoenix departments responded to help fight the fire.
Officials say the sprinkler system helped contain the fire after several pallets of merchandise caught fire.
After the fire was extinguished, investigators were able to discover the incident was caught on surveillance video.
