Legacy: Gangsters, Corruption and the London Olympics

When billions poured into the neglected east London borough hosting the 2012 Olympics, a turf war broke out between crime families for control of a now valuable strip of land.

Using violence, guile and corruption, one gangster, the Long Fella, emerged as a true untouchable. A team of local detectives made it their business to take him on until Scotland Yard threw them under the bus and the business of putting on "the greatest show on earth" won the day.

Protecting the Olympic legacy by covering up a scandal of suspicious deaths and corruption seemed more important than protecting Londoners from the predatory Long Fella and his friends in suits. For others at Scotland Yard, the crime lord was simply too big and too dangerous to take on.
