FBI Special Agent Gregory Jones says 42 year old Gregory Todd Bowden, of Byron, was arrested Wednesday.
According to the FBI, Bowden had numerous telephone and internet conversations with a woman who, he believed, was the mother of a young girl. The daughter, Bowden was told, was under the age of 10.
Investigators say the deputy came to Atlanta to have sex with both the mother and the girl.
The FBI says both the mother and daughter were fictional. Bowden was taken into custody after arriving at a predetermined meeting place.
