"Train bosses have come under fire for not prosecuting a wealthy hedge fund manager who was described as the “biggest fare dodger in railway history”, evading more than £42,000 in train tickets. The City executive is believed to have dodged the fare for the 82-minute commute between the Sussex village of Stonegate and central London for five years.
He exploited a flaw that allowed him to go through barriers at Cannon Street station in London by “tapping out” with an Oyster travelcard.
After finally being caught by a ticket inspector, the executive was able to pay £42,550 in dodged fares and £450 in legal costs within three days of being asked to pay up as part of an out-of-court settlement."
