Hearing the recent story of an absconding bookie at Listowel reminded me of this character who turned up at Epsom on Derby Day in 1997 and laid the nuts off (the appropriately named) Entrepreneur at fancy prices before doing a runner.
A very clear photo of him was circulated soon after but I am not sure if he was ever apprehended.
"….It might pay to study the name on the betting tickets he [was] handing out. The conman at Epsom on Saturday gave his name as John Batten, but the name on his tickets was … Lucan."
