A London casino chasing USD 14 million in cheques bounced by a high-rolling Middle Eastern gambler has lost an attempt to recover the money from an Arab bank. Grosvenor Casinos, owner of the Clermont Club, sued the National Bank of Abu Dhabi (NBAD) in an attempt to recover debts owed by gambler called Ahmed al-Reyaysa. Ahmed al-Reyaysa is known on London’s gambling circuit, and is said to have gambled USD 199 million in 18 months.
