JONESBORO — Clayton County investigators have arrested about 20 people in an undercover operation targeting prostitution and drug activity.

Sheriff Kem Kimbrough tells WSB-TV that several residents had complained about crime in the area. He says the sting was part of an attempt to keep sex trafficking, drugs, and violent crimes out of the heavily traveled Tara Boulevard corridor.

The undercover operation came after several weeks of surveillance in the area. Investigators say increased cooperation from business owners and employees when they see crime would make their work more effective.
