Dani Alves was arrested Friday on suspicion of sexually assaulting a woman in Spain.
According to police, the alleged act took place on December 31 at a nightclub in Barcelona.
Alves will now face charges before a judge, who will make a decision.
In Spain, sexual assault can include anything from unwanted sexual groping to rape. Police said they couldn’t go into specifics about the case.
Dani Alves is one of soccer’s most successful players, having won major titles with a number of elite clubs over his long career, including Barcelona, Juventus, and Paris Saint-Germain. He is currently a member of Mexican club Pumas.
The defender was a key member of Barcelona’s golden years, playing on the team’s right flank alongside Lionel Messi from 2008 to 2016. With the Catalan club, which he briefly rejoined last season, he won the Champions League three times.
