It's the type of contraption you don't want to find anytime, anywhere.
"It had wires attached to it. When we got there, there was an unknown part attached to it that was covered with tape. The wires ran into that," said officer Kevin Pollard with the Metro Police Department's Hazardous Devices Unit.
"It wasn't just a wrapped up coke can. It was definitely planned out," Pollard said.
It's happened twice now in one week.
Surveillance cameras caught a man walking into a cash advance business on Thompson Lane, robbing the place at gunpoint then leaving a fake explosive behind.
"She truly believed that it was an actual explosive device," Pollard said.
One week before it happened at the Cash Express in Lebanon. Police think the two might be related.
"We've had hoax devices before when it was a wire wrapped around a remote control. There was more thought that went into these two: the one in Lebanon and in this one," Pollard said.
The crook is still on the loose, so officers said chances are it will happen again.
"He could probably repeat it. Also with the publicity these two have gotten, there could be copycats," Pollard said.
As for the timing, officers said it couldn't be worse.
"In light of what's recently happened across the United States people are more on edge these days," Pollard said.
Investigators do want locals to be highly aware. Just because the last two were fake, they said, doesn't mean the next one will be too.
"We don't want anyone to assume it's not an explosive device. Devices have been in the United States before that have been detonated by movement, by time, by light. It's only the imagination of the bomb maker," Pollard said.
Police said the man caught on a surveillance camera is about 5'9" and weighs approximately 190 pounds. At the time of the robbery, he wore a dreadlock wig, a tan crochet hat, large sunglasses and a mask. He also carried a tan messenger bag.
