Victor Chandler, one of Britain's best-known bookmakers, is understood to be one of a group of bookies arrested during the Arc de Triomphe meeting at Longchamps on Sunday for illegally taking bets. The group, including Chandler's nephew and rails representative Butch Beaton-Brown, were caught in a raid on the corporate facility for British racegoers run by Horse Racing Abroad, who take around 1,300 punters to the Arc in Paris every year.
