This is the kind of case that worries both police and citizens. For one, police don't know how far the fake cop will go.
The news travels fast.
"I woke up this morning and saw a news van parked right over here and said hey what's going on."
It was last night around 11 at the Bristol Park Apartments where Ana lives.
"I heard about some guy dressed up as cops and they stole this guys money."
Police say two men who looked like police officers approached the victims. the fake cops appeared to have and badge, walkie-talkies and guns. The victims were frisked, their pockets emptied and the criminals made off with a wad of cash.
"Most of our undercover officers are going to have a uniformed officer involved at some point."
Sgt. Bob Rohloff on how to spot the fakes.
"We have officers that are working on the gangs unit they are wearing a jersey, its blue with yellow writing that says Tulsa Police."
"They'll also have their hard badge and are to have their commissions at all times."
But the criminals are also getting their hands on equipment being passed off as real.
"There's bad apples everywhere."
Mark Hulett, at Oklahoma Police Supply where only real cops can buy the police badges and other insignia.
"None of the badges can anyone just walk in and buy one that says sheriffs department or police department."
This brings to mind another problem. Cars that resemble unmarked police cars. We found this example back at the Bristol park apartments. This car looks a lot like this one on a traffic stop. One way to spot the fake is the red and blue lights in side mirrors. And when in doubt...do what Maria does.
"Well at school they teach us a lot of things. One of them was call 9-1-1."
