VALRICO, Fla. — A Walmart in Valrico is back open after a brief evacuation on Saturday. 

The store was evacuated after a FedEx truck behind the store caught fire. 

A shopper sent us video of the huge plum of smoke, which looks like it's coming from the building.

Hillsborough County firefighters were able to quickly put out the flames, however, they did have to ventilate the area, which is why they evacuated the store out of precaution.

Fire Rescue officials said it appears the fire started in the cab area of the truck. 

The cause of the fire is still underinvestigation.
