text: A married Mormon elementary school teacher had a sexual relationship with one of his 12-year-old students - and was only stopped when her classmates told other teachers, police have revealed. Kenne Worthen, 27, allegedly started flirting with the sixth grader at Longview Elementary School in Phoenix last August and the relationship turned sexual in January, Fox10 reported. The father-of-one allegedly kept in contact with the girl outside school by messaging her on an iPod app, Google Hangouts, where she labeled his profile with a fake name, 'Jesse Smith'. Some of the conversations were sexual in nature, according to police, while in another, the teacher told the student he was worried she would feel guilty and tell his wife or the police.

Arrested: Kenne Worthen, pictured left in his mug shot and right in his teacher's headshot, was arrested on Friday after it emerged that he allegedly had a sexual relationship with one of his 12-year-old students . Earlier this year, he allegedly asked her mother if the girl could stay behind after class. On April 10, they had sexual contact at the school, the girl told police. 'He contacted my daughter's mother and said, "Can she stay after school and help with something?" and mom said, "Of course, why not?"' the girl's enraged father told Fox10. 'There should've been no reason why my child was in a classroom alone with a teacher.' The father, who has not been identified, called the alleged relationship 'sickening' but applauded his daughter's fellow students, who told another staff member last Friday that they thought Worthen and the student were having inappropriate contact. 'I honestly couldn't thank them enough for what they've done for my daughter in this case, because who knows how much longer this would have gone on had they not said anything,' he said. After the students told staff, they called the police, according to a statement from the school district. When asked about the relationship, the girl initially denied it but later admitted to it, according to KPHO.

On Monday, Osborn School District Superintendent Patricia Tate sent a letter to parents about the incident. 'He has been put on administrative leave and will not be returning to Longview,' the letter read. 'If anyone has information or questions specific to this case, please contact the Phoenix Police Department at 602-262-6151. The safety of your children is and always will be our first priority.' Police said they do not believe there are other victims. Speaking to Fox10, the girl's father said he was overwhelmed with anger towards Worthen. 'You have this anger, the anger towards the perpetrator, and a feeling that you physically want to harm that person,' he said. 'Then there's an anger at least for me towards the school, because you send your child there thinking they're going to be safe.' In court: Following his arrest on Friday, the teacher appeared in court (pictured) but was denied bond .
