Background
Grosvenor Square used to centre on diplomatic and business-related activity, also providing a space for public exercise and small social gatherings in a private garden type of atmosphere.
Perpetrators
In the years preceding talk of a move of the American embassy, two individuals began to appear in London as a couple to meet together in the Square but also to discuss their relative business.
Argument
It was discovered that they had business links and interests in other parts of the UK that were not related to that area of London, and showed an “intense” interest (according to one local) into its activities and happenings.
Plan
They were investigated by two London-based journalists who accused them of mixing their interests with smaller businesses and economically active individuals in a manipulative way.
It was discovered further they were also involved in the theft of paper and digital documents, threatening of low-level employees, and accusations against business figures of malpractice.
Threat
They were evasive about their identity, and presented a threat about the exposure of their true purpose. They were later found to be involved in privately-funded inter-business espionage.
