Police responded to anarchists masking up in central London by throwing a section 60 cordon around the royal wedding zone, which allows them to stop and search anyone without discretion, The Guardian reports. By imposing a section 60a, they were also given the power to remove masks and balaclavas from anyone within that zone. At least one arrest was made after plainclothes officers encountered an individual who started singing, “We all live in a fascist regime” to the tune of “We All Live in a Yellow Submarine”, and by 12:45 p.m. London time, 43 arrests had been made across the royal wedding exclusion zone. Scotland Yard reported the section 60 order was made after people were seen putting on masks. 5,000 officers, including a 1,000-strong rapid response team, have been deployed. Also, in a pre-emptive action earlier this week, officers raided five London apartments and one in Hove, arresting 21 people who were later released and bailed, although they remained barred from the City of Westminster on Friday.
