A 14-year-old student at Evanston Township High School was charged Monday with criminal sexual assault after allegedly forcing a 15-year-old girl to perform a sex act on him.
A school safety officer came upon the pair in a school stairwell during school hours, according to a notice posted to the school's website.
During an investigation, the girl reportedly told authorities she'd performed the act against her will.
The teen boy was taken into custody and charged with a class 1 felony. He's in custody at the Cook County Juvenile Detention Center.
Due to their ages, the students' names were not released.
