Grosvenor Casinos has resorted to legal action after an Arab high roller wrote two cheques worth nearly £7m that bounced.

Ahmed Al-Reyaysa exchanged the cheques for chips at the Clermont Club in London.

After he spent the money playing roulette, the casino discovered that the individual did not have enough money in his bank account to honour the cheques.

The Clermont has since gone to the High Court to try to reclaim the cash.
