Girl dragged by school bus in Louisville, Kentucky

New disturbing surveillance video shows a bus driver in Louisville dragging a young girl after her backpack got stuck in the door.

Police said the bus dragged the child about 100 feet.

But, neighbors described the distance as being at least a football field.

A passing driver finally got the bus to stop.

Jefferson County school officials have launched an investigation.

The little girl was scratched up, but not seriously hurt.
