scorpio is right - unless this guy did something illegal that caused the business to fail, which seems unlikely, I don't see how he can be guilty of anything.

You're right to say there are two sides to the story, in so much as this guy may be exaggerating things for effect (by using the word hostage, for example), but I don't see how there can really be a side to this story that justifies a court case against him which results in him not being allowed to leave Qatar.
