Dallas ISD is facing questions about the way district police officers handled two incidents last week, including one in which an officer is seen on video body-slamming a 12-year-old girl.

In grainy footage, two girls are seen fighting at Piedmont G.L.O.B.A.L Academy when the officer steps in and separates them. The officer then picks up the girl and slams her to the ground, KXAS-TV (NBC5) reported.

The girl was suspended for three days and hospitalized with a clavicle fracture, which her mother said was a result of being slammed into the ground, not the fight, NBC5 reported.

She told the station that the officer also pepper-sprayed the student.

The district declined an interview with NBC5 but released a statement saying the video shows the after-school fight and "captures a Dallas ISD police officer who attempts to end the disruption; however, his actions do not appear to represent the type of response we want our officers to display."

The officer has been placed on administrative leave while an investigation is conducted.

The girl's mother told NBC5 she wants the officer fired. She said she is weighing whether to hire an attorney and said other students recorded the incident but were told to delete the videos by a school official.

In a separate incident on May 9, Dallas ISD police reportedly handcuffed a 7-year-old boy at Gabe P. Allen Charter School because he was acting out — something that happens often, his mother told KDFW-TV (Channel 4).

The boy's mother said police used excessive force on her son, who has attention-deficit hyperactivity and mood disorders and is in the special needs program.

She also said the school called to say there had been a problem with her son, but when she went to pick him up she was told he had been taken to a behavioral health care facility, NBC5 reported.

Dallas ISD said it could not comment on the claims because of confidentiality laws. A district spokeswoman said the actions by district police were their own and not a matter of district policy.

District police did not return messages from the Associated Press.

The family has hired an attorney and blamed the incident on a "failure in training," NBC5 reported.

David Ramirez, an investigator hired by the family's attorneys, said the boy was sedated at the behavioral facility and admitted without notifying a parent. He spent nearly a week there and was released Monday afternoon.

The attorney said the family was told their son was released after it was determined he no longer posed a threat to himself, KDFW reported.

A photo of the boy in handcuffs was circulated on social media. In response, the district sent a note to parents asking that they help "not continue to spread misinformation," KDFW reported.

"The image you may have seen posted is of a student while he is being restrained to protect himself against any further harm," the statement said.
