A married teacher in Oklahoma was arrested for allegedly having sex with a student amid the statewide teacher walkout.

Keri Hoffman, 35, admitted to police Saturday that she had sex with a 15-year-old student before and after they attended a massive teacher rally protesting pay cuts at the state Capitol, news station KWSO reported.

Hoffman, a Clinton Middle School teacher, and the teen reportedly became sexually involved on the last day of classes before the strike began April 2, according to news station KFOR.

She went with her husband Saturday to the police department, where she allegedly confessed to having sex with the student on numerous occasions.

Hoffman told authorities that she used Facebook to message the boy and arrange the sexual encounters, which occurred inside her car and her dad’s garage.

The pair also allegedly had sex last week before and after the teacher walkout protest at the Capitol.

The algebra teacher gave a ride to a group of students, including the victim, picking him up first so they could have sex, according to police. Hoffman told investigators they had intercourse again that evening when she dropped him off at home.

Hoffman was booked into Custer County Jail on numerous charges including rape. She is being held on $30,000 bond.
