TAMPA (CBSMiami.com) – Police in undercover prostitution stings hear a lot of requests from suspects that are trying to determine if the customer is a cop or not.

But, one officer in Manatee County, Florida found a unique way to get around one prostitute’s test to see if he was a cop.

According to the Manatee County Sheriff’s Department, an undercover officer was working in a prostitution sting last week when he picked up a suspected prostitute.

The woman rode with the officer briefly and they stopped at a 7-11 for him to use an ATM. The officer said he threw three $20 bills out in the car and told her he only needed enough money to pick up some groceries.

According to the police report, the woman then asked undercover officer to expose himself. The officer asked if he could put on a condom first. He then exposed a “flaccid rubber replica of a penis and put a condom on it,” the police report said.

The woman began to perform oral sex on the fake phallus, according to the Manatee County Sheriff’s Department. The officer said he then saw an opossum cross the road and slammed on the brakes, “causing the female to slide out of her seat and mildly into the dashboard.”

The officer then drove to another location and asked what the price was for her services. She finally revealed it was $20 for oral sex; when the officer approved of the price, the suspect was taken into custody by sheriff’s deputies who were monitoring the entire incident.

She was later identified as Christina Vavra, according to the Manatee County Sheriff’s Department.
