A white Baltimore City middle school teacher has been fired after she called her students the N-word in a science class and told them they “are going to get shot.”

The incident on Tuesday at Harlem Park Middle/Elementary School was recorded on a cellphone, and the video spread on social media. In response, the Baltimore City school system issued a brief statement denouncing the teacher’s “racially charged comments” and “verbally abusive behavior.”

“At Baltimore City Public Schools, we are committed to creating positive and equitable learning environments in school communities where all members are welcome, supported, and valued,” the school system said in the statement. “No form of discriminatory behavior of any kind is or will be tolerated.”

The Baltimore teacher’s union on Thursday also issued a statement condemning the teacher’s use of the N-word to describe her black middle school students.

“The Union stands together with Baltimore City Public Schools in supporting respectful and equitable learning environments for all our students,” the union statement read.
