Prosecutors have filed charges in a story we broke on FOX 26 two months ago.
Harris County Juvenile Detention Officer Robert Robinson is accused of sexually assaulting a teenage inmate.
The teen's parents spoke exclusively with FOX 26 back in August.
"He was messing with her and sneaking in and out of her cell."
"I can't believe that this happened to my child who was locked up and supposed to be in protective custody that this happened."
Prosecutors tell us they also have a video tape of Robinson's encounter with the teenager in her cell.
