There was panic at a Florida mall after a smash-and-grab robbery was apparently mistaken for gunfire.

Authorities say three men appeared to have used a sledgehammer to smash the glass of a Rolex store at International Plaza in Tampa.

Police believe that patrons mistook the sound of smashed glass for gunshots.

The mall was locked down for more than an hour amid the chaos.

No one was injured, but the suspects are still on the loose.
