The New York Racing Assn., which runs the Aqueduct, Belmont and Saratoga thoroughbred tracks, was stuck with $263,900 in bad checks by one patron during a five-day period in 1986, state Comptroller Edward Regan reported.

Regan also said an audit of NYRA by his office uncovered a scam run by parking-fee collectors that may have cost the association more than $250,000 in 1987 and ’88.

NYRA President Gerald McKeon confirmed that the association had been hit for more than a quarter-million dollars by one player who wrote bad checks at Aqueduct in the spring of 1986 but he refused to identify the person.
