Despite the sensationalized news reports about the Suffolk Murders and the nightclub shootings in Ipswich, crime is no more rampant here than in any other similar-sized town. Avoid getting into confrontations, particularly in bars, as things get a bit nasty. There are several no-go areas at night - most noteably Chantry, Gainsborough and Greenwich, as well as the residential areas around Norwich Road, although the average tourist will find no need to go to these areas, and if you stick to the main arterial roads you'll be safe. Avoid using Derby Road train station at night as it's poorly lit, isolated and unstaffed. Be careful of parking your car in quiet residential streets at night, or leaving your car in a privately run 'budget car park' such as the one at the waterfront, as car break-ins and car-thefts are common - use a town-centre car park operated by Ipswich Borough Council or NCP instead.
There's a strong rivalry between Ipswich Town FC and Norwich City FC - on match days avoid wearing football colours or saying things that may provoke a football-related confrontation. That said, the rivelry here is not as serious as it is between for example Birmingham City and Aston Villa in Birmingham; or Chelsea and Arsenal in London and football hooliganism is rare.
