London CNN —Several anti-monarchy protesters were arrested in central London ahead of the coronation of King Charles III on Saturday, their group has said, as the Metropolitan Police force faces scrutiny for its approach toward demonstrators at the historic event. Thousands gathered in central London on Saturday to celebrate the once-in-a-generation event. But it also drew demonstrators, with protesters wearing yellow T-shirts booing and shouting “Not My King” throughout the morning. Republic, Britain’s largest anti-monarchy group, told CNN that police – without providing any reason – arrested organizers of the anti-monarchy protest. There are also plans for facial recognition technology to be used in central London, which has sparked criticism from human rights groups.
