A married teacher in Oklahoma was arrested Wednesday after she was accused of sending nude pictures and having sex with an underage student, according to local media reports Thursday.

Hunter Day, 22, a science teacher at Yukon High School, was placed in the Canadian County Jail on multiple charges, including second-degree rape, with a bond set for $85,000.

The arrest was made by the Canadian County Sheriff’s Department on complaints of second-degree rape, facilitating sexual contact with a minor and possession of child pornography, according to KWTV, a CBS affiliate in Oklahoma City.

Authorities investigated Day's relationship with her student after the boy's parents raised a complaint after they found explicit pictures and messages on his phone.

A press release from the sheriff’s office claimed the forensic examination of the phone revealed that Day, who is reportedly married to the school’s football coach, had sex with the student and the two also had plans to meet at the teacher's residence Wednesday afternoon.

Deputies arrived at Day's residence and reportedly texted the teacher from the boy’s phone saying he’d arrived, to which she responded saying, “The doors [sic] unlocked as usual.” The Sheriff’s Department said that it had set up the teacher to get more evidence in the case.

When investigators entered the home, they found Day sitting on the floor of her living room with candles lit and all the lights off. The teacher confessed to sending the boy illicit pictures and said he’d also sent her pictures of his genitals, KWTV reported.

“I’m no longer surprised by the people who commit these crimes, because predators come from all walks of life,” Canadian County Sheriff Chris West told the outlet.

“This is a classic case of a serious breach of public trust,” he said. “School teachers are entrusted to protect and educate our children, not to engage in an unlawful sexual relationship with them.”

In a statement, administrators from the high school said “the safety and well-being of our students is our number one priority,” and there was no indication in Day’s record that she would make such a “very poor decision.”

The school also said that it is cooperating with the authorities in their investigation.

Just a month before her arrest, Day spoke with station News9 about her decision to get an emergency certification to teach science at the high school. Day, who is a graduate of Oklahoma Baptist University, said she always wanted to go to medical school, but had a change of heart a couple of months prior and decided to try her hand at teaching.

"I definitely see teaching as something I could do forever which is not something I would have said six months ago," Day said at the time. She added that she was nervous about teaching because she thought students would not take her seriously due to her young age.

There have been other recent incidents of inappropriate relationships between teachers and students in Oklahoma City. In April 2016, a 51-year-old high school teacher was arrested for sending an explicit video to an 18-year-old student. In June 2016, a 26-year-old teacher in Choctaw was arrested for lewd or indecent acts with a 13-year-old.
