An 8-year-old girl was hospitalized Tuesday morning after police say her older brother shot her in the chest with a pellet gun in North Philadelphia.

Police said the two boys, ages 10 and 12, were playing with pellet guns shortly before 11 a.m. on Etting Street near Berks when one of them shot their little sister in the chest. It was unclear whether it was an accident.

The girl was taken to Hahnemann University Hospital by police, then later transferred to St. Christopher's Hospital for Children. She is in stable condition.

Police said the two boys were taken into custody, and officers recovered two pellet guns loaded with pointed ammunition.
