WEST HILLS (CBSLA.com) — A 9-year-old claims a classmate broke her arm—and another girl’s arm—during an after-school program at an elementary school in West Hills.

Kaylee Cottrell, who attends Hamlin Street Elementary School, said she was playing tag with a 10-year-old boy and her friend last Thursday when the boy became violent.

“First, he shoved (my friend) into the window, so I jumped in and told him to stop,” she said.

Kaylee said when she tried to protect her friend, the boy told her, “What are you gonna do about it?”

“Then he pushed me against the table and hit me,” she said. “He took my arm, he twisted it, pulled back, and then pulled up.”

A supervisor, who students call a coach, was outside playing kickball when the girls were injured.

“I told him. I asked for an ice pack and he said, ‘No, your arm looks fine,’” Kaylee said.

The Los Angeles Unified School District confirmed the incident to KCAL9′s Serene Branson and said the supervisor was terminated.

Tiffany Cottrell, Kaylee’s mother, said the district needs to do more to discipline the young boy.

“Something has to happen. He brutally attacked these girls. This wasn’t just kids playing,” she said. “To this day, the boy has not been suspended. He’s only (been suspended) from the after-school program. He’s still in her class.”

Kaylee said, “I feel scared. I feel like I’m going to get hurt again.”

On Tuesday, Branson reported that parents were upset they weren’t notified by Hamlin Street administrators about the assault.

The adults said they’d like the 10-year-old to seek counseling or be removed from the school.
