Bryana Phelan of Chicago has been charged with 15 counts of misconduct, officials said.

“Phelan socialized with an in-custody youth-a male over the age of 17-by having multiple phone conversations with him and driving him around in a facility vehicle for personal reasons outside the scope of Phelan’s duties,” a news release form the Kane County State’s Attorney’s Office read in part. “It is further alleged that Phelan had a sexual relationship with the same in-custody youth in that she made multiple phone calls of an offensive or sexual nature with the youth; attempted to engage in sexual acts during a phone call; and facilitated, encouraged, and watched the in-custody youth masturbate in front of her.”

Phelan was ordered to appear in court September 18.

No further information was immediately available.
