An Ohio school district has acknowledged that a teacher made a mistake after a black student reported that he was told he might be lynched if he didn't get back to work.
Tanisha Agee-Bell says a white teacher at Mason Middle School made the comment to her 13-year-old son during class in December.
Mason schools spokeswoman Tracey Carson says educators sometimes "mess up." She says the teacher did not mean to offend the student.
A statement from the district says it has seen an uptick in racially insensitive comments, sometimes arising from "genuine ignorance." Officials have pledged to continue providing cultural sensitivity training.
Agee-Bell says the district should remove the teacher from the classroom.
