The camapaigners were trying to draw attention to local arms dealers EDO MBM.
The march left Churchill Square (Brighton's main shopping mall) with intention of marching to the Level. Police (some drafted in from the Met) blocked North Road and with a large audience of shoppers and bystanders attacked the crowd. Four arrests followed. One arrest of an eighty year old man visibly shocked the general public.
The march starts a week of action against EDO MBM, for more info visit www.smashedo.org.uk
