Two teenagers face juvenile charges for allegedly participating in a sex act on the school bus in Rockdale County.

According to the Rockdale County sheriff's office, the alleged sex act took place on the bus home from Alpha Academy in Conyers during the first week of school.

Bus surveillance video shows the 16-year-old boy and 15-year-old girl sitting next to each other.  The boy buckles his belt after it's over.  It appears others on the bus were aware of what was going on.

The 16-year-old boy is charged as a juvenile with child molestation and the 15-year-old girl faces a sodomy count.
