HEBRON, Maine (AP) _ A parent ran on the field and shoved a referee who made a disputed call at the end of a middle school soccer tournament game, sparking a mini-melee.

The referee pushed the man back, and a woman then slapped the referee in the face as spectators swarmed the field, according to Maine State Trooper Kyle Tilsley. Holy Cross beat Monmouth Middle School 1-0 in the title game Saturday.

The National Association of Sports Officials receives two to three reports a week of violent parents at sporting events. The main targets of the rage are coaches and referees.

In one highly publicized case, in Reading, Mass., a father unhappy with the way his son's hockey coach was handling a practice was accused of beating the coach to death in July.
