A Kennesaw Mountain High School student accused of sexually assaulting a disabled 17-year-old girl was removed from the school, Channel 2 Action News reported.

The student has not been arrested, and no charges have been filed in the investigation, which began in December.

The girl’s mother told Channel 2 her daughter was raped “on the stairwell between the upper gym and lower gym” at the school. The school said surveillance footage does not indicate an assault took place there.

The alleged victim was taken to Children’s Healthcare of Atlanta, where a rape kit was performed.

A report was filed with Kennesaw police on Dec. 22 and authorities have collected the victim’s clothing, but investigators are still in the process of gathering forensic evidence, Channel 2 reported. Charges, if any, will not be filed until police receive the results of the forensic analysis.

The girl, who has a cognitive disorder according to her  mother, missed school for a month.

“I’m scared for her every day,” she said. “I fear for her every day.”
