After all, the Belgian guy was the representative of the Belgian part and was nominated as administrator of the business. When he accepted the position, that probably mean a nice salary and allowances, he should be aware of the responsibilities he have. Everywhere in the world, the owner of the company can ask to receive compensation for the loss. He should not ask for resignation from his Belgian company without being sure that all the debts between parts are covered. It is very nice to receive 100 000QAR salary and to live like a king without being responsible for nothing. It is his fault and according to any management contract he is fully responsible. He must go to court and face the reality. After all, the only thing he can do is to ask his former employer for compensation.
Sorry for him, but the prisons are fulfilled with "inocent" peoples.
