A man has been arrested over allegations of a hate crime against Manchester City winger Raheem Sterling at the club's training ground.
Greater Manchester Police said a 29-year-old man was in custody on suspicion of racially aggravated assault and the incident was being treated as a hate crime.
"Racism will not be tolerated in Greater Manchester and has no place in civilised society," Detective Chief Inspector Paul Walker said in a statement.
"We take every report incredibly seriously."
Sterling scored twice in City's 4-1 defeat of Tottenham Hotspur at the Etihad Stadium on Saturday evening. The club has yet to comment.
