A 22-year-old teacher in the US state of Oklahoma was arrested on Wednesday (15 November) for allegedly sending nude pictures and having sex with an underage student.

Hunter Day, a science teacher at the Yukon High School, is currently placed in the Canadian County Jail. Day, who is reportedly married to the school's football coach, is facing charges of second-degree rape, facilitating sexual contact with a minor and possession of child pornography. Her bond was set for $85,000 (£64204.25), News9 website reported.

The investigation for the case began after authorities were contacted by the student's parents after they found explicit text messages and nude pictures of the student and the teacher on the boy's phone, the Canadian County Sheriff's Department office stated.

According to a press release from the sheriff's office, the forensic examination of the phone revealed that the two were supposed to meet at her residence.

The deputies who went to Day's residence, reportedly texted her from the boy's phone saying he'd arrived. Day replied to the message saying, "The doors [sic] unlocked as usual".

The investigators who entered the house reportedly found Day sitting on the floor of her living room with all the lights off and candles lit.

Day has confessed that both of them have sent illicit pictures to each other.

"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 News9.

"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," he added.

Yukon Public Schools Superintendent Dr Jason Simeroth told Oklahoma News 4 channel: "We were informed late Wednesday afternoon that an employee of the district was arrested for engaging in an inappropriate relationship with a high school student,"

"This behaviour was representative of a very poor decision by a person entrusted with teaching our students," Simeroth said.

Just a month before her arrest, Day, who is a graduate of Oklahoma Baptist University, had spoken to News9 channel about her decision to get an emergency certification to teach science at the high school. Day said that she wanted to go to a medical school, but changed her mind a couple of months back and decided to start teaching.

"I definitely see teaching as something I could do forever which is not something I would have said six months ago," During the interview, she also mentioned that initially, she was nervous about teaching because she thought that the students won't take her seriously because of her young age.
