A high school reading teacher working at a school near Milwaukee has been arrested after allegedly having sex with a 16-year-old male student in her classroom twelve times.

30-year-old April Novak resigned from her job at Menomonee Falls High School after the police opened the investigation earlier this month.

Another teacher at the school had contacted school administrators December 11th after seeing Mrs. Novak and the teen embracing and kissing in her classroom.

Authorities believe they had intercourse and oral sex on the school grounds starting around the middle of October. She told investigators she understood the teen was underage, but said they had “very strong feelings for each other.”

She and the unnamed teen had agreed to keep their relationship a secret.

Mrs. Novak was charged with 12 felony counts of sexual assault of a student by school staff this past Tuesday, a day after her husband filed for divorce.

She’s being held in lieu of $100,000 bail and faces up to six years behind bars and a fine of up to $10,000 for each count of sexual assault, if she’s convicted.
