A student at Lamar High School in Houston, Texas, was caught on video punching a teacher in the face Thursday, KHOU-TV reported.
The violence apparently was over a confiscated cell phone.
In a clip used by KHOU that blurs the faces of the student and teacher, the student is seen right up in the teacher's face and demanding his phone back.
A raw video of the altercation shows the student ordering the teacher, "Gimme my f***in' phone, [N-word]!" After repeated demands from the student, the teacher tells the student, "Go sit down." With that the student socks the teacher in the face with an audible thud, after which screams are heard.
KHOU said the school's principal sent a note to parents that reads, "We do not condone and will not tolerate this type of behavior. It is always our top priority to maintain an environment where our students and staff are safe. Administrators will be looking into the cause of the altercation and continue to evaluate ways to prevent these occurrences in the future."
