Referee shot dead in Argentina after showing player red card
The tragedy happened in an amateur match in Campo de la Ribera in the Cordoba province, with 48-year-old official Cesar Flores the victim.
Police have started a manhunt for a player who retrieved a gun from his bag and shot the referee three times after being given a red card.
"It all happened during the football match," a police source told Efe, a local news agency.
"We don't know [exactly what took place] but it appears the player was angry, fetched a gun and killed [the referee]."
Local reports state that Mr Flores was shot in the head, neck and chest before the assailant fled.
Another player was also caught up in the incident, with 25-year-old Walter Zarate receiving a non-life-threatening injury.
The match was abandoned after the shooting.
Football in Argentina has been marred by a host of unsavory events over the last 12 months.
Five players were sent off in an ill-tempered friendly between Buenos Aires heavyweights Boca Juniors and River Plate last month. Boca player Carlos Tevez was head-butted before a 40-man brawl erupted.
