The crime of armed robbery had been 'brought to a state almost of perfection' in the 1970s thanks to police corruption, a new documentary reveals. The final episode in BBC series Bent Coppers: Crossing the Line of Duty, which airs this evening, reveals how one of London's most senior police officers was believed to have helped suppress investigations and even took cuts of robbers' ill-gotten gains. Commander Hugh Moore, who was the third most senior officer in the City of London Police, was allegedly 'the greatest villain unhung', a fellow corrupt officer said. Moore, who died from heart failure in 1993 while attempting an arrest, was described as a 'greedy b*****d' by bent detective Phil Cuthbert, who talked of a £175,000 robbery on the Daily Express's payroll van in 1976 being a 'Hughie Moore job'.
