A transgender student who identifies as male was suspended from his South Carolina high school after a teacher saw him using the boy’s bathroom, WMBF reports.

The child, who wishes to remain anonymous, appears to be caught between a rock and hard place. When he began transitioning in middle school, he continued to use the girls’ bathroom — prompting complaints that there was a boy in the girls’ bathroom. So the middle school allowed him to use the boys’ restroom for three years without incident.

That ended at Socastee High School when a male teacher was leaving the boys’ bathroom as the student was going in, WMBF reports.

“He must’ve looked at his records and saw the sex on his records because that’s the only way he could’ve known,” the student’s mother said.

The next day, the boy was called in by administrators and told he must use the girls’ bathroom or go to the nurse’s office.

“If he started using the girl’s bathroom in 12th grade, it’s going to create a problem. I felt like that would be dangerous,” his mom said. “The nurse’s office is downstairs on the first floor of the school and the school has three stories.”
