Britain’s Gambling Commission has fined a casino operator £1.8m and given it a formal warning on the issues of social responsibility and money laundering failings.

Silverbond Enterprises, owner of the Park Lane Club in Mayfair, London, also had additional conditions added to its licence as a result of the Commission’s investigation.

The location had failed to recognise the indicators of potential problem gambling, such as a customer displaying violent behaviour which included threatening staff and damaging of property; a customer asking for his winnings to be transferred to his personal bank account to prevent him playing further; and a customer of the casino asking to increase the maximum amount that could be deposited by cheque.

The money laundering failings, said the Commission, included the operator’s compliance procedures not detailing how anti-money laundering policies were to be implemented and failing to carry out enhanced due diligence on 61 customers.

Two personal management licence holders at the club have also received formal warnings and informed that they must improve their record on protecting players and preventing money laundering.
