The EncroChat hack has given the police unprecedented access to the secrets of organised crime. Nearly four years on from the hack, the detective who led the Met’s EncroChat investigation, DCI Driss Hayoukane, reveals what the police have learnt about OCGs which they didn’t know before. Presenter Mobeen Azhar hears about the impact of the EncroChat operation from Driss and from the National Crime Agency. There have been thousands of arrests, 200 threats to life averted and tonnes of drugs seized. But has taking out the kingpins cut crime? Catching the Kingpins is a BBC Studios Production for BBC Sounds.
