No action over Stamford Bridge 'monkey gesture'
A man who was arrested on suspicion of racist behaviour after Chelsea's League Cup win over Manchester United on 31 October will face no further action.
Pictures taken during the fourth-round tie at Stamford Bridge appeared to show a fan making a "monkey gesture".
Manchester United striker Danny Welbeck appeared to be the target of the alleged abuse.
Scotland Yard said a decision was taken with the Crown Prosecution Service to take no further action.
After the 28-year-old man was arrested, officers interviewed other fans in the crowd and examined CCTV footage.
A Scotland Yard spokesman said: "The Metropolitan Police Service takes any allegation of racist chanting and/or behaviour very seriously and if any matters are brought to our attention they will of course be thoroughly investigated."
He added that the service worked closely with football clubs and partner agencies to monitor behaviour "to ensure public confidence and safety".
