A Texas woman says her 12-year-old daughter was suspended from school following an altercation with another student that ended with a police officer body-slamming the girl to the ground.

Gloria Valdez says her daughter, a student at a San Antonio middle school, suffered swelling to her temple after being thrown to the floor by the school district officer.

She acknowledged to the San Antonio Express-News (http://bit.ly/23ihtn6 ) that the girl has fought with others before but said another student started the March altercation.

Students used cellphones to record the officer as he struggled with the girl before slamming her to the ground. The officer has been placed on paid leave.

In the video, the officer appears to handcuff the girl before having her stand and leading her away.
