Operation Tiberius was an official internal Metropolitan Police investigation, commissioned in October 2001, written in 2002, but leaked to The Independent newspaper in 2014. The Metropolitan Police have acknowledged it was born of other investigations, but describe it as a new strategic approach to corruption, rather than a single operation. According to The Independent, the gangs used their contacts inside Freemasonry to “recruit corrupted officers”. The report concluded that this was one of “the most difficult aspects of organised crime corruption to proof against”.
