(KMOV.com) -- A St. Louis teacher faces charges for a physical confrontation with a female student.
Peter Sheppard, 33, was charged with assault after authorities reviewed video shot by another Gateway Stem High School student.
The video shows Sheppard throwing down a chair before shoving a 16-year-old student.
The student said Sheppard was upset because she wanted to watch movies in another class and he did not want her to go.
The district has placed Sheppard on leave.
