A 46-year-old Calhoun man has been arrested on child porn charges.

Robert “Duane” Crosby was arrested Monday and charged with three counts of sexual exploitation of children, according to the Georgia Bureau of Investigation.

In a GBI undercover investigation, initiated by DeKalb County police, an individual using the screen name “niteblood” was identified as having several files of suspected child pornography available for sharing. The GBI determined the individual lived in Calhoun, about 70 miles north of Atlanta along I-75. The GBI and Gordon County deputies executed a search warrant at Crosby’s home in the 200 block of Clairmont Drive SE in Calhoun.

Several images and video files of suspected child pornography were found, according to the GBI.

Crosby was taken to the Gordon County Jail.
