SALISBURY, N.C. — A school bus driver was charged with assault on a child in Salisbury, according to police.

Investigators said the principal at Overton Elementary contacted police about the incident on the bus involving a 7-year-old student who has autism.

A court date was set for February 20. The child was not hurt in the incident.
