 On the morning of 14 June , the crowd continued west along the Thames , burning the houses of officials around Westminster and opening the Westminster gaol . They then moved back into central London , setting fire to more buildings and storming Newgate Prison . The hunt for Flemings continued , and those with Flemish @-@ sounding accents were killed , including the royal adviser , Richard Lyons . In one city ward , the bodies of 40 executed Flemings were piled up in the street , and at the Church of St Martin Vintry , popular with the Flemish , 35 of the community were killed . Historian Rodney Hilton argues that these attacks may have been coordinated by the weavers ' guilds of London , who were commercial competitors of the Flemish weavers .
