Johnny was a petty crook who helped Frank Bradley rob Dave Smith's Betting Shop of its takings in September 1971. The long-haired man spent most of the day in the shop, waiting for Lucille Hewitt to make her way to the bank with the takings. While he waited, Johnny got friendly with the punters and even helped Stan Ogden with a bet. When Lucille made her move, Johnny phoned Frank and told him he could catch her at Bessie Street. Frank mugged Lucille and gave her a knock on the head, leaving her with shock and a concussion.
