Three children were rushed to the hospital Saturday following a dirt bike accident on a Delaware County road. Police say a 10-year-old boy was driving a nine-year-old girl around on the dirt bike, when they hit the boy’s four-year-old sister. The boy and his younger sister had to get stitches. The nine-year-old girl suffered a broken arm. None of the injuries were life-threatening. Police say the kids’ mother was out of sight but nearby when the accident happened.
