Appeal to Man Utd and Man City fans over Wembley clash
The Metropolitan Police have warned troublemakers to avoid the Community Shield match between Manchester United and Manchester City at Wembley.
The rivals are due to play in the football season's curtain-raiser fixture on Sunday.
The Met said it would "deal robustly" with anybody intent on causing trouble at the game.
"Stay away and let genuine fans enjoy the game," said Ch Supt Julia Pendry, police commander for the game.
Police advised fans that Wembley was "a public transport only venue" and added that any fans without tickets should not turn up for the match.
Ch Supt Pendry said: "This friendly match is a great way to kick off the football season and for fans and families to see some good football in a world famous venue.
"I would say to anyone who is coming along with the aim of causing trouble that we have a range of tactics in place to deal with these disruptions."
