Five activists arrested in G20 'bomb plot' as London goes into lockdown for world leaders

Barack Obama defied violent protests and political wrangling ahead of today's G20 summit to celebrate America's 'special relationship' with Britain. But as Britain fell under the spell of Mr Obama and his wife Michelle last night, anarchy was unleashed in the City of London. One protester died after a mob stormed the Royal Bank of Scotland and besieged the Bank of England. Police were pelted with bottles as a medical team tried to revive the demonstrator, who had collapsed at a makeshift camp being set up near the Bank of England. The man, who was said to be in his forties, was pronounced dead from natural causes shortly after arrival at hospital.
