Seven people have been taken to a hospital after a horse jumped over a high fence into a crowd of about 50 spectators during the Grand Annual Steeplechase at Warrnambool race track.

Banna Strand, without a rider, veered off course Thursday and jumped a 7-foot (2-meter) brush fence into the crowd.

The most serious injury was to a 2-year-old girl, who suffered a fractured collarbone. Most of the other injured were treated and released at the hospital.

Racing Victoria says it will investigate the incident.
