LARGO (FOX 13) - The smell of an unknown chemical emptied a Largo Walmart this afternoon.
Several people complained of coughing fits and scratchy throats, so officials evacuated the store on Missouri Avenue after the odor permeated the building.
The view from SkyFOX showed at least 10 emergency vehicles on the scene, but around 3 p.m., the all-clear was given. Employees could be seen to be filing back into the store.
There's no word about the source of the smell.
