Police say the majority of arrests were for displaying placards in support of the banned group.

British police said they arrested 474 people in central London on Saturday as supporters of a recently banned pro-Palestinian group intentionally flouted the law as part of their effort to force the government to reconsider the ban.

Police in London have detained more than 466 people who were protesting the United Kingdom’s decision to ban the Palestine Action Group, marking the “largest ever mass arrest” at a single protest in the British capital, according to campaigners.
