RIK PRINCE, founder of the now-defunct mercenary firm Blackwater and current chairman of Frontier Services Group, is under investigation by the U.S. Department of Justice and other federal agencies for attempting to broker military services to foreign governments and possible money laundering, according to multiple sources with knowledge of the case.

What began as an investigation into Prince's attempts to sell defense services in Libya and other countries in Africa has widened to a probe of allegations that Prince received assistance from Chinese intelligence to set up an account for his Libya operations through the Bank of China. The Justice Department, which declined to comment for this article, is also seeking to uncover the precise nature of Prince's relationship with Chinese intelligence.
