A Norwalk woman is demanding answers after she says her child's health and safety were put in jeopardy during a ride home on the school bus.

Natalie Ward says her 9-year-old daughter was left with a head injury Tuesday after someone threw a rock through the school bus window. Ward says her daughter's head was bleeding and she later developed a large bump. She took her daughter to the emergency room where she received a CT scan.

According to Laidlaw Bus Company, the bus driver pulled over immediately following the incident and contacted police. News 12 Connecticut's call to Kendell School, where the girl attends class, has not been returned.
