DISTRICT HEIGHTS, Md. –

A 7-year-old girl at Thomas Claggett Elementary School in District Heights, Md., was beaten unconscious by at least four classmates Tuesday morning.

It happened during recess in the school’s gymnasium.

The little girl’s parents say their daughter was taken by ambulance to Children’s Hospital in D.C. She was diagnosed with a mild concussion.

Her mother, Phersephone Holland, says she can’t believe it happened at school.

“That’s my baby. I bring her to school and that’s the least thing I expect is a phone call informing me that my daughter is unconscious,” she says.
