A high-rolling gambler who failed to honor a £2.2m casino debt was sentenced to 10 months in jail on Thursday.

Safa Abdulla Al Geabury, a Swiss-based businessman, was convicted last July of failing to pay a £2m marker he’d rung up at the members-only Ritz Club Casino in London during a frenzied night of roulette play in February 2014.

Al Geabury (pictured) had refused to honor his debt based on his claim that Ritz staff had improperly enticed him into returning to their casino despite his having signed a self-exclusion form. But the UK’s High Court found Al Geabury an “intemperate witness” whose personal worth of £1b could easily take the hit and thus the gambler was ordered to pay the casino the full amount plus interest.

On Thursday, Mr. Justice Spencer found Al Geabury in contempt of court for having “deliberately chose to do nothing to comply” with Spencer’s order to make with the money. However, Spencer said Al Geabury could reduce his 10-month sentence to six months if the Swiss scofflaw “promptly” complies with Spencer’s original order to pay up.
