A 28-year-old man has been arrested over an allegation that a racist gesture was made to a footballer during a Chelsea match against Manchester United.
The man was arrested this afternoon after attending a west London police station by appointment, Scotland Yard said.
A spokesman said: "He was arrested on suspicion of a racially aggravated Section 4a Public Order Act offence and currently remains in custody at the west London police station. Inquiries continue."
Detectives have been investigating a complaint regarding alleged racist behaviour at Stamford Bridge on October 31 during Chelsea's Capital One Cup win over Manchester United.
