A man has been arrested at Wembley after a picture emerged of a football fan wearing a jersey with what appeared to be a reference to the Hillsborough disaster printed on the back. The Metropolitan Police Events Twitter account retweeted a picture of a man wearing a Manchester United shirt that had the number 97 on the back and the words “Not Enough”. Manchester City beat their rivals Manchester United in the FA Cup final at Wembley on Saturday. Sharing a tweet posted by an account called Liverpool Photos, the Met’s events Twitter account said: “We are aware of this and have worked proactively with officials at @wembleystadium to identify the individual. He has been arrested on suspicion of a public order offence and taken into custody.” Ninety-seven football fans died as a result of a crush at a match between Liverpool and Nottingham Forest at Hillsborough Stadium in Sheffield on 15 April 1989. They were unlawfully killed amid a number of police errors, an inquest jury ruled in 2016.
