An Oregon teacher has been accused of having a sexual relationship with a student.

Axar.az reports citing Dailymail that, Andrea Baber, 29, was arrested at her Cottage Grove home on Friday just days after she and the teenager were reportedly caught in bed by her husband on December 5, reported The News-Review.

Law enforcement first learned of the relationship last week after the boy's father received an anonymous email asking whether he knew his teenage son was in a sexual relationship with Baber.

Attached to the email were several photos of Baber and the boy in bed together, according to court documents.

Baber worked at Logos Christian Academy in Springfield where she taught Language and Literature, Writing II and Speech Communication.

Lt Chris Merrifield of the Douglas County Sheriff's Office says the relationship began in 2016, when the male student was 15 years old.

Merrifield added that the relationship continued 'on a regular basis', with Baber also providing the boy with marijuana, reported The Register-Guard.

Baber is charged with third-degree rape, third-degree sodomy, unlawful delivery of marijuana to a person under 18 years of age, online sexual corruption of a child and contributing to the sexual delinquency of a minor.

She is being held on $456,250 bail at Douglas County Jail.

The sheriff's office identified Baber as a former teacher, but she remains on the school's online staff directory. The website says Baber lives south of Eugene with her husband, a dog and a cat.

According to the site: 'Andrea has always felt called to work with youth and is very excited that God opened the door for her to be part of the Logos team.'
