The reported murder took place in Campo de la Ribera, the provincial capital of Cordoba, Argentina, on Sunday.

Police reportedly said the player retrieved a gun from his bag after receiving the red card, returned to the field during the game and shot the 48 year-old referee.

Authorities are apparently still looking for the player responsible and are still trying to piece together what happened. A police source told Efe news agency: "It all happened during the football match. We don't know [exactly what took place], but it appears the player was angry, fetched a gun and killed him."

Local reports said the referee was shot three times, in the head, chest and neck, while another player was injured, but not critically.
