I don't think this justifies his treatment, but the article starts off by essentially saying this man did nothing wrong and was forced into signing a confession without a lawyer present in a language he can't understand. It's not until you get more than a third of the way into the article that they point out he was convicted in a civil case brought by the same complainant in British courts of committing financial fraud against the Dubai bank.
His treatment is unacceptable, the sentence is outrageous (and counterproductive), but fundamentally this is why you don't get into business with and especially don't defraud petty dictators in unstable regions of the world. If this had been in his place of birth, he would have been murdered rather than imprisoned, and I imagine he should be well aware of this given his upbringing and career history.
