A San Antonio school police officer has been put on paid administrative leave after a video of him slamming a 12-year-old girl onto her face surfaced online.

The 33-second video shows Officer Joshua Kehm struggling to restrain a student at Rhodes Middle School.

Kehm lifts the girl off the ground and slams her face-first to the ground, appearing to knock her unconscious for a moment.

Kehm then handcuffs the dazed girl before picking her up and walking her away.

The officer responded after two students began arguing outside Rhodes Middle School on March 29, school district spokeswoman Leslie Price said.

“The video is very disturbing,” Price said, adding that the department has launched a formal investigation into the incident. “The officer was placed on leave this morning.”
