Police have issued a message to supporters, and the community, ahead of the Watford FC v Luton Town Championship encounter at Vicarage Road Stadium this weekend.
The match will kick-off at 12pm on Sunday, October 23, with both the Hornets and the Hatters set to lock horns in the famous derby game.
Chief Superintendent Nick Caveney, said: “The game between the two clubs is something to be celebrated and we have been working with both clubs to plan ahead of the fixture.
“We have a clear message for those coming to Sunday’s game.
“If, as the majority will be, you are attending to enjoy the game and the experience of a competitive derby match then you are welcome with open arms and we hope you have a great time.
“However, the rivalry is not an excuse for disorder or anti-social behaviour and this will not be tolerated, therefore we will be on hand to prevent trouble.
“A significant policing presence, more than is usually seen at matches at Vicarage Road, will be in the area due to the derby and our main aim is to promote public safety.
“At the end of the game measures will be in place to ensure both sets of fans are able to leave the stadium in a more structured manner.
“We want everyone who comes to enjoy the game in a safe environment.”
