Four women soccer players with River Plate, one of Argentina's top professional clubs, were released by Brazilian authorities on Friday following their detention last week after allegedly targeting a ball boy with racist slurs.

Four players from the River Plate women's team who were arrested for an alleged racial slur during a match have been released, the Sao Paulo state's prison administration secretariat said.

Brazilian authorities ruled to keep four Argentine soccer players in preventive detention on Monday after their alleged involvement in a racist incident during the Ladies Cup tournament in Sao Paulo state last week.
