The Spanish league on Wednesday denounced racist insults by a Barcelona fan against Real Madrid midfielder Vinicius Junior during the Clasico at the Camp Nou Stadium on Sunday.
The league said it will take the case to Spanish authorities so they can pursue the necessary measures against the fan.
It did not say when the incident took place during the match won 2-1 by Madrid. No other details were immediately provided. The 21-year-old Brazil international started and played most of the game.
The league last year condemned racist insults by Espanyol fans against Athletic Bilbao forward Iaki Williams.
