US school suspends student for filming teacher using racial slur

A US high school is facing criticism after it suspended a student for recording her teacher using a racial slur in class.

Mary Walton, who is fifteen, filmed her teacher saying the n-word repeatedly at Glendale High School in Springfield, Missouri.

Her family has since retained a lawyer and asked the school to apologise.

School officials said they believe the student was disciplined appropriately.

The teacher who used the slur has quit.
