Chelsea have banned a fan for life for using “racially abusive language” towards Manchester City’s Raheem Sterling during a match at Stamford Bridge on 8 December 2018.
Five other Blues supporters have been temporarily suspended for using “abusive language and threatening and aggressive behaviour”.
Police investigated allegations England forward Sterling was racially abused but the Crown Prosecution Service said there was insufficient evidence for a criminal charge.
Chelsea conducted their own investigation and said they delayed reaching their decision so as not to prejudice the related police inquiry.
The Blues said they operated under the civil standard of proof, rather than criminal.
“While the club respects the decision of the CPS, the question 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,” said a Chelsea statement.
