A former Georgia police officer who used his position to steal drugs and money has pleaded guilty to charges of extortion and drug trafficking conspiracy, federal officials said.

Ex-Auburn police Cpl. Charles F. Hubbard, 51, of Loganville, conspired with at least five other people to steal money and transport drugs and “assisted drug traffickers for his own financial gain,” U.S. Attorney John Horn said Friday.

In January 2015, one of Hubbard’s conspirators ordered six kilograms of cocaine, Horn said. Hubbard used his police vehicle to intercept the drugs. Afterward, wiretaps revealed that Hubbard agreed to conduct a traffic stop on an individual carrying drugs in exchange for $5,000.

On April 4, using his police vehicle and wearing police clothing, Hubbard seized a confidential source’s money, Horn said. Hubbard gave the source a receipt from the “East Metro Drug Task Force” so the seizure would look official. The task force does not exist. Hubbard then released the confidential source and met with two conspirators to split the money.

Hubbard was arrested at a shopping complex off Chamblee Tucker Road in Atlanta, The Atlanta Journal-Constitution previously reported.

During a search of Hubbard’s vehicle, officers found additional unused blank sheets in the name of the non-existent task force that Hubbard had manufactured, Horn said.

Hubbard was fired from the Auburn Police Department after the arrest. Auburn is about 40 miles northeast of Atlanta.

Sentencing for Hubbard on drug trafficking and conspiracy charges is scheduled for Nov. 7.
