A Louisville area school system has fired a bus driver who inadvertently dragged a 7-year-old girl about 500 feet when her backpack got caught in the door, reports say.

Driver Melinda Sanders was fired in June by the Jefferson County Public Schools, which said she failed to follow proper procedures in the incident May 15, local media outlets reported.

Police said the first-grader was getting off the bus when the door shut on her backpack, trapping her alongside the bus as it drove away. Taken with minor injuries to a hospital, the child was released two days later.

A district letter to Sanders said she was distracted by talking with another student and failed to check the stairwell before shutting the door, the reports say.

Sanders couldn't be reached immediately.
