Teacher caught on camera shaking, shoving students

Parents want answers from school officials in Detroit after a video captured a substitute teacher becoming physical with third-grade students.

The incidents took place Friday at Mackenzie Elementary-Middle School, according to sources who provided the video to WJBK. In the video, a male substitute teacher can be seen outside the classroom shaking a male student by the shoulders. In a second incident, the teacher shoves back a female student to prevent her from entering the classroom.
