ONCE upon a time off the Old Kent Road, a gang of armed robbers stole £6million from a security van – with the help of some washing up liquid. The bandits took just 65 seconds to move two steel cages, each containing £3million in used £20 notes, from the armoured truck into a box van after dousing the floors with Fairy Liquid. 7 The Fairy Liquid gang stole £6 million in 65 seconds - before being arrested minutes later Credit: Rex 7 One of the gang, Patsy Henderson, has spoken out for the first time and claims they were set up Credit: Alamy Despite the weight of the cages, the cleaning fluid let the team glide them on to their getaway truck, catching out cops who thought it would take up to eight minutes.
