(HOUSTON) -- A Houston jailer has been charged with sexual assault of a child after he admitted to trading candy and treats for sexual favors with an incarcerated 15-year-old.
In a taped interview, Robert Emerson Robinson, 28, admitted to having sex with the teen girl while he was working at the Harris County Juvenile Justice Center.
According to the criminal complaint, the May 23 incident was revealed after the teenager came forward, saying she allowed Robinson to have sex with her "because he had provided her with candy and treats while she was incarcerated."
Surveillance footage on the fourth floor of the detention center from May 23 shows Robinson entering a cell housing the teenager. Robinson entered the girl's cell during a time when the lights were off. In the footage, only Robinson's arm is exposed in the doorway, according to the complaint.
Robinson told investigators that he "made a mistake," and that the teen was telling the truth about the sexual activity. He has been charged with sexual assault of a child under age 17.
It is unclear if he has been fired from his job. Calls placed by ABC News to Kendall Mayfield with the Harris County Juvenile Probation Department were unreturned.
Robinson was released from custody at the Harris County Jail after posting $30,000 bond, court records indicate.
