Vinicius was involved in a fracas with Sevilla players late in the game at the Sanchez Pizjuan and a man in the crowd is shown making a racist gesture towards the Brazil attacker in images published online.
The 23-year-old thanked Sevilla after the Andalusian club released a statement after the game in which they revealed the fan in question had been ejected from the stadium.
"A member of the public was identified, ejected from the stadium and handed over to legal authorities," they said.
"The individual will also be subject to the club's vigorous internal disciplinary protocols and have their membership revoked.
"Sevilla FC condemns all racist and xenophobic behaviour and will work closely with the authorities to ensure that action is taken accordingly. This behaviour does not belong at Sevilla FC."
Vinicius later took to social media to discuss the abuse, the latest in a long line of incidents he has suffered over the past couple of years, claiming he had also been targeted by a child at the Sanchez Pizjuan.
"Congratulations to Sevilla for acting quickly and for the punishment in another sad episode for Spanish football," he said.
"Unfortunately I have access to a video of another racist act at this Saturday's game, this time carried out by a child. It's so sad that there is no one to educate her. I invest, and I invest a lot, in education in Brazil to train citizens with different attitudes.
"The face of today's racist has been published on websites as on several other occasions. I hope the Spanish authorities do their part and make changes to legislation once and for all. These people need to be criminally punished too."
And he added: "It would be a great first step to prepare for the 2030 World Cup [which Spain will co-host]. I am here to help. Sorry to sound repetitive but it's episode number 19. And counting."
