In 1972, Skelhorn gave bank robber Bertie Smalls, Britain's first true supergrass, immunity from prosecution in light of the amounts and detail of his Queen's evidence.
Throughout the 1970s, the supergrass was a feared tool that the police had begun using which is generally considered to have begun with Bertie Smalls, who, faced with a hefty prison sentence for his part in leading his gang of armed robbers, the 'Wembley Mob', decided to turn 'Queen's Evidence' against his fellow thieves which resulted in them receiving heavy prison sentences whilst Smalls was granted immunity from prosecution.
