John Saccone told KTRK-TV, Houston, he was on his way home from his check-cashing business around 9 p.m. Saturday when the men appeared behind him. They turned on red and blue lights and told him that he failed to use a turn signal.
The suspects, who were wearing the word "police" across their chests and backs, then "arrested" Saccone.
In a few minutes, a real Houston police officer drove up and became suspicious of the supposed unmarked unit with Missouri license plates. He arrested the two men immediately.
"I saw the shotgun and the duct tape on the car. My assumption is they were planning on taking me back to my store to force me to open up my store and possibly rob me," Saccone said.
He said he knows one of the suspects, a former co-worker.
