LOUISVILLE, Ky. (WDRB) -- A Bullitt County Public Schools teacher has been arrested and charged with raping a 17-year-old student who was enrolled in one of her classes, police said.

According to an arrest report, 24-year-old Crystal Chappell was employed as a teacher with the school system when she engaged in sexual intercourse with the student on eight different occasions, beginning in June 2014.

When questioned by the Shepherdsville Police Department about the allegations, Chappell allegedly admitted to having sex with the student. She said six of the occasions took place inside Bullitt County, while two additional incidents took place outside Bullitt County.

Chappell was arrested by the Shepherdsville Police Department Saturday morning and charged with six counts of third degree rape. She is currently incarcerated at the Bullitt County Detention Center.

Police say she admitted to having sex with underage student

"These are very rare instances," said Bullitt County Schools Attorney Eric Farris.

A Shepherdsville Police report says Crystal Chappell, 24, admitted to the allegations that she had sex with an underage student.

A judge entered a not guilty plea for Chappell in district court Tuesday and set her bond at $25,000 cash. 

According to the arrest report officers took her to jail Saturday morning. It says she unlawfully engaged in sexual intercourse with a 17-year-old student six different times since June.

The report also says Chappell admitted to the allegations.

Farris says he was told by officers that the sex did not happen at Bullitt Central High School, and according to the arrest report, Chappell even admitted to having sex twice outside of Bullitt County.

The district found out about the alleged sexual relationship on Thursday because other students were talking about it.

"And it was determined it was appropriate to refer the matter to Shepherdsville Police Department," said Farris.

Farris says the district immediately suspended Chappell, a third year math teacher, without pay.

"In this particular instance this lady is charged only at this point. We don't know if she's guilty or not, these are mere allegations."

"I have her as my honors Algebra One teacher," said freshman Triston Hillard. She told WDRB News that students can't stop talking about the allegations.

"I think it's nasty because she was older,” she said, “but she does teach in high school. Even if the kid was under 18, they should know better and she should know better, it's just common sense."

Farris says the district does full criminal background checks including talking with references. It's also constantly reminding teachers how they're supposed to interact with the kids.

"Don't text students, don't have any kind of social media contact,” said Farris. “It's repeated throughout the year. It's one of those things that should be common sense."

Farris says if Chappell did admit to charges to police she will never be hired back and likely have her teaching license revoked in Kentucky.
