SAN ANTONIO, Texas (KXAN) – An investigation is underway after a 12-year-old student was body slammed by a police officer at a school in San Antonio.Warning: the video may be hard to watch for some viewers. 

The incident happened last week after an argument at school. The student, Janissa Valdez, was left with a bump on the head but is expected to be okay.

KXAN’s sister NBC station WOAI found that the incident occurred in the school hallway as a fight seemed like it was going to break out between the Valdez and another girl.

The student and her mother are now speaking about the officer’s use of force. When asked about the incident Valdez said, “I wasn’t going to do anything.”

She claimed moments before the interaction with an officer she “was going up to her to tell her let’s go somewhere else so we could talk but that’s when the cop thought I was going at her,”

Her mother said, “You could hear where she just hits the ground it was nothing but concrete…..like cement.”

The officer is on paid leave during the investigation conducted by the San Antonio Independent School District.
