Suffolk Constabulary are warning supporters that there could be delays and movement restrictions around the ground when Leeds United visit Portman Road on Saturday.
The last time the sides met, at Elland Road at the end of the 2006/07 season, the game was held up for 30 minutes after Leeds fans staged a pitch invasion and threw coins and other missiles at Town’s travelling support.
Chief Inspector Paul Bradford, who is overseeing a policing operation involving more than 100 police officers, called on supporters to behave in a responsible manner: "This will be an exciting game for both teams.
"We hope that people celebrate the match sensibly and in the right spirit. We will not tolerate anti-social behaviour, violence, racial chanting, mindless vandalism or any alcohol-fuelled disorder.
"We will continue our use of firm but fair policing to ensure the safety of those attending the game and those members of the public wishing to go about their normal business.”
Fans are warned to be prepared for crowd and traffic congestion and disruption on the day. Car sharing and the use of public transport is suggested, while the Portman Road car park will be used for the away supporters coaches, limiting space.
