Four individuals have been arrested in Spain for allegedly orchestrating an online hate campaign targeting Real Madrid's Vinicius Jr., urging fans to wear masks and racially abuse the player during a derby match against Atletico Madrid. This campaign used the hashtag #MetropolitanoConMascarilla and was linked to significant social unrest, prompting LaLiga to call for arrests. Despite no racist incidents reported during the match, the game was paused due to objects thrown onto the field. Spanish police have not disclosed the identities of the arrested individuals, and investigations continue, possibly leading to more arrests. This case follows a precedent set in June, where three Valencia fans were sentenced for similar offenses against Vinicius Jr. LaLiga, along with the Spanish Football Federation and clubs, have increased vigilance against racism, with Atletico Madrid emphasizing a zero-tolerance policy.
