Petty, taken into custody Aug. 1, is being held in the Cumberland County Detention Center under a $325,000 secured bond.
The charges stem from incidents involving two females ages 12 and 14.
The incidents with the 14-year-old occurred from March through June of 2003 and involved the statutory charges. The incidents with the 12-year-old occurred from January through July of 2003 and are related to the two first-degree rape charges.
The investigation began on July 26, when the 14-year-old told her mother about an incident with Petty. The mother notified the sheriff's office.
The incidents involving the 12-year-old were investigated as a result of information obtained in the original investigation.
Petty was charged with one count of indecent liberties in October of 2001. He was out of jail on pre-trial release pending a court action.
