Federal prosecutors say a metro Atlanta police officer and another man have been arrested on corruption, drug and weapons charges.
Investigators say Clayton County police officer Dwayne Penn conspired with accused drug dealer Adrian Austin to arrange a fake traffic stop involving a car they believed was holding six kilograms of cocaine.
Authorities say the person they were looking to set up was actually a confidential federal informant.
Officials say Penn and Austin waited while the informant conducted a staged drug deal with another undercover agent in Decatur Wednesday.
Investigators say Penn drew his gun on the informant, ordered them into his car, took four kilograms of fake cocaine and let the informant go with two kilograms.
The two were arrested soon afterward and it's unclear if they have attorneys.
