The effigy of Brazilian striker was hung with a noose around its neck ahead of the Madrid derby against Atletico in January.

He was offered disgusting monkey chants by Atletico fans in a La Liga clash four months earlier.

Vinicius, 22, had to face racial abuse for several times, especially the most during the recent match against Valencia that Madrid lost. Spanish national police confirmed they had finally taken action.

The police said: "Three of the detainees are active members of a radical Madrid club fan group.

“The inquiries carried out up to now by investigators through DNA evidence, evidence from witnesses and other intelligence material led to the identification of four males as the alleged authors.

“Officers discovered three belonged to an ultras organisation and had already been identified during previous high-risk matches by police operatives seeking to prevent sporting violence.

“They were arrested in an operation carried out today which was coordinated with Madrid’s Court of Instruction Number 38 and a prosecution cyber-crimes section.”
