Harris served as a Premier referee for three seasons but three major incidents marred this period. In May 1999 he sent off three West Ham players as they lost heavily at home to Leeds United. David Elleray was fourth official. After the game Harris narrowly escaped being attacked by home supporters as he waited in his car at traffic lights.† This led to a new policy by the Premier League where all officials are transported to games by people-carrier, to reduce the risk of such an event.
