A substitute teacher from Texas is facing aggravated assault charges after she was caught on video violently assaulting a 15-year-old secondary school student.

The shocking footage shows the substitute teacher brutally beating and stomping on the 15-year-old girl, who is a special needs student at Lehman High School in Texas in the US. The video, which was filmed on a cell phone, quickly went viral on social media.

The 32-year-old substitute teacher is free on a $10,000 bond but could face up to 2 to 20 years in prison if convicted.

According to the attorney of the victim's family, the class was being loud before the incident and the situation escalated when the teacher started cursing at the students. The victim allegedly told the teacher not to talk to her that way. The attorney added that her client suffered "severe injuries" and still suffered from blurred vision and memory loss resulting from brain injury. The young teenager also suffered post-traumatic anxiety.

The incident stirred waves of public outrage. School officials published a statement last Friday: "As a Hays CISD family, when one of our schools and students is hurting, we all hurt. You may have already seen stories on the news tonight, or the video on social media, about a horrible incident that occurred late this afternoon at Lehman High School. "It was a traumatic event for the student, her classmates, and the teachers and staff at Lehman High School. Let us all keep the Lobos in our hearts this weekend. I know we all wish our student and her family well as she recovers from this assault."

The incident and the school district are currently under investigation.
