Vinícius Jr., Real Madrid’s Brazilian forward, was subjected to persistent racist abuse during his team’s 1-0 defeat to Valencia at the Mestalla Stadium in Spain’s La Liga.

The flashpoint of the game came in the second half, where after a stoppage in play, an animated Vinícius pointed out a fan in the stands for the abuse before engaging with the supporters in the section of the crowd in question.

LaLiga TV broadcasters said there was an announcement in the stadium calling on fans to not insult the players or throw objects onto the pitch.

The referee’s official report from the game described the incident.

“Racist insults: in the 73rd minute, a spectator from the southern ‘Mario Kempes’ tribune directed himself towards player No. 20 of Real Madrid CF Mr. Vinicius José De Oliveira Do Nascimiento, screaming at him: ‘Monkey, monkey’ which led to the activation of the racism protocol, notifying the pitch delegate so that a corresponding warning over the loudspeaker would be made. The match was halted until said announcement was aired over the loudspeaker of the stadium,” it reads.

Video from the match broadcast by DAZN España also showed that, in addition to the aforementioned incident, the Real Madrid star was subjected to various other racial insults throughout the game.

Spanish national police in Valencia told CNN on Monday that they identified one person in the stadium who was involved in alleged racist chanting, but so far no arrests have been made. In a statement on Monday, Valencia confirmed that local police had identified one fan and that the fan in question and any others involved in racist gesturing or acts would be banned for life from the stadium.

The Spanish Prosecutor’s Office told CNN on Monday that it has opened an investigation into the incident for a potential hate crime.
