The City bonds robbery of 1990 was a heist in which £291.9 million was stolen in London, England. The carefully planned operation made it seem at first as if a courier had been mugged on 2 May, yet the City of London Police soon realised that it was a sophisticated global venture which ended up involving participants such as the New York mafia, the Provisional Irish Republican Army (IRA), and Colombian drug barons. The robbery was one of the largest in world history.
