“Nothing that I saw,” a shopper told Diamond. “I’m sorry this happened because you don’t want to put a stain on something that’s so good.”

Another woman at the department store said the incident has her on edge.

“Now I’m going to think twice. If something like that can happen at 6 a.m., there’s no telling what can happen when the sun goes down,” a shopper named Nicole told Diamond.

One shopper said he was not surprised by the robbery attempt at the new department store.

“Hey, here’s a new potential pot of gold. Let’s see how easy it is to dip into Fort Knox here. You’re going to have to have beefed up security in uniform,” a man said.

Police are reviewing surveillance videos to try to identify the attempted robbers.
