The incident, which drew national attention last week, took place in August. High school freshman Sandra Garcia said she had gotten her hair done for an event that evening and didn't want to ruin it by getting it wet.
"He starts to bring me down and I had sat myself on the stairs thinking that he would stop, but he grabbed me by my ankles and started to pull me down," Garcia said. "I was just telling him like stop. Leave me alone. You can't be touching me."
Garcia took photos of her bruises from the struggle. Her attorney is expected to file a claim against the district.
District officials declined to comment because the alleged incident involved a minor.
The teacher, Danny Paterson, faces a misdemeanor injury to a child charge and was placed on paid leave. He could lose his job if convicted.
