Timothy Fitzgerald Willingham Jr., 19, faces two counts of felony child molestation and one count of felony sodomy, Athens-Clarke County police spokesman Geof Gilland said in a statement.
Authorities said the alleged molestation occurred Tuesday, but school officials weren't notified until Friday.
Police reviewed surveillance footage from the bus and saw Willingham, a student at Clarke Central High School, and two girls, ages 15 and 16, engaged in a “sexual incident,” Gilland said.
The school district sent parents a letter notifying them of the incident.
