US police hunt arsonists after fireworks prank led customers to think they were being ‘shot at’

Police in the US are looking to speak to three people in connection with an act of arson at a Walmart store in Phoenix, Arizona.

In footage released to the public, two men and a woman can be seen entering the aisle where the fireworks are on display just before the blaze starts.

As the fire takes hold, employees can be seen franticly trying to pull more fireworks off shelves in an attempt to stop the fire from spreading.
