I used face recognition app to hunt man behind whisky fraud

I have spent years investigating serious criminals. From human traffickers and gunrunners to contract killers and cocaine smugglers. One thing I never thought I'd end up investigating was whisky. BBC Producer Liam McDougall told me of a source he had – a whistleblower – who said that organised crime had infiltrated the whisky industry, that he had compiled a hitlist of suspect whisky investment companies, and would we be interested in looking into it? One of those on the list was a company called Cask Whisky Ltd.
