A video shows driver Cedric Dhéran's horse going offstride during a race this past Sunday at the race course, and it would appear that the driver felt he was backed into or interfered with in some manner by the driver in front of him at the time -- Manu Rotsaert. Dhéran then accelerated his offstride horse, pulled up beside Rotsaert and began to hit him in the upper body with his whip and then used his own horse to run Rotsaert's horse off the track.
