LaLiga filed an eighth complaint regarding racist abuse directed at Real Madrid forward Vinicius Junior following incidents in Sunday's clash with Barcelona.
The hosts secured a 2-1 Clasico win at Camp Nou following Franck Kessie's 92nd-minute strike, which opened a 12-point lead for Xavi's side over Madrid.
That victory has been marred by racist abuse towards Vinicius, however, with LaLiga confirming a complaint had been lodged to the Barcelona Court of Instruction.
A statement read: "In view of the events that took place at the FC Barcelona-Real Madrid match, in which intolerable racist behaviour was once again observed against Vinicius Jr, LaLiga has reported the racist insults to the Barcelona Court of Instruction.
"This is the eighth complaint filed by LaLiga with the corresponding authorities for racist abuse against Vinicius Jr."
Earlier this week, Mallorca announced a fan's membership had been revoked for three years after racist abuse was directed at Vinicius and Villarreal's Samuel Chukwueze.
In February, Real Valladolid suspended 12 season ticket holders for abusing Vinicius during a league match two months earlier.
