A teacher's aide at a Milwaukee high school has been arrested after he was captured on cellphone video pushing a student to the floor and grabbing him by the throat.

Warning: Video contains graphic language.

The 17-second video taken at Bay View High School doesn't show what led up to the confrontation Wednesday, but it shows the 39-year-old aide shoving the 14-year-old boy into some classroom furniture and then holding him to the floor by the neck.

Milwaukee Public Schools spokeswoman Denise Callaway says police were called to the school as soon as administrators learned about the incident. The student was taken to a hospital for treatment of minor injuries.
