A married teacher in Oklahoma was arrested Wednesday and accused of having a sexual relationship with an underage student, KWTV reported.

Hunter Day, 22, who teaches science at Yukon High School, was arrested by the Canadian County Sheriff’s Department on complaints of second-degree rape, facilitating sexual contact with a minor and possession of child pornography, KWTV reported. She is reportedly married to the school’s football coach.

The sheriff’s office said the investigation began when they were reportedly contacted by the boy’s parents. The boy’s cell phone allegedly contained explicit text messages and nude photographs, the sheriff’s office told KWTV. Authorities did not reveal the age of the boy, except to note that he was underage.

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

Investigators said Day and the boy had arranged a meeting on the day of the arrest, KWTV reported. When deputies arrived at the home, they sent Day a text message from the boy’s phone, saying, “I’m here.” Day allegedly responded, “The doors [sic] unlocked as usual.”

Authorities said when they entered Day’s house, they found her sitting on the living room floor with the lights turned off, wearing a Christmas cat T-shirt and workout shorts. She allegedly admitted to sending “bra and panty” photographs of herself to the boy, and also allegedly said she had received photos of the boy’s genitals, KWTV reported.

During a news conference on Thursday, the Yukon Schools Superintendent Jason Simeroth said he could not comment on Day’s status with the school, pending the investigation.

Day was booked into the Canadian County Jail. Her bond was set at $85,000.
