In August 2016, son of a former Prime Minister of Gabon, who worked for Och-Ziff's Africa Management Ltd, a subsidiary of the U.S. hedge fund Och-Ziff, was arrested in the US and charged with bribing officials in Guinea, Chad and Niger on behalf of the company to secure mining concessions and gain access to relevant confidential information. The investigation also revealed that he was involved in rewriting Guinea's mining law during President Conde's rule. In December 2016, the US Department of Justice announced that the man pleaded guilty to conspiring to make corrupt payments to government officials in Africa.
