Chelsea have banned a fan from Stamford Bridge for life for using racially abusive language and threatening and aggressive behaviour.
It relates to a Premier League match with Manchester City last December - after which Raheem Sterling complained about comments directed towards him.
Five further individuals have been temporarily excluded from attending Chelsea home games for between one and two years.
Chelsea say they'd delayed taking action in order to not prejudice a criminal investigation into the incident but the Crown Prosecution Service have since opted not to bring charges.
"While the club respects the decision of the CPS (not to charge the individual with a criminal offence), the question that it had to determine was not whether a criminal offence had been committed, but rather whether the individual acted in breach of the ticketing terms and conditions," a club statement read.
"In this regard, the club operates to the civil standard of proof, which is entirely different to the criminal standard.
"In reaching its decision, the club took into account the denial made by the individual as well as a range of other evidence, including video evidence and evidence from two lip-reading experts - both of whom advised that the individual had used words that are racially abusive."
