Where the majority of British police forces have silver-coloured badges, those of the City of London Police are black and gold featuring the City crest. The force has rare red and white chequered cap bands and unique red and white striped duty arm bands on the sleeves of the tunics of constables and sergeants (red and white being the colours of the City), which in most other British police forces are black and white. City police sergeants and constables wear crested custodian helmets whilst on foot patrol. These helmets do not feature either St Edward's Crown or the Brunswick Star, which are used on most other police helmets in England and Wales.
