Following controversy over Executive Outcomes role in providing military forecs as security, often for mining projects in Africa, Mann went on to establish Sandline International with Tim Spicer in the mid-1990's.
On September 10, 2004, Mr. Mann was sentenced to seven years in prison by a Zimbabwean magistrate for trying to illegally buy weapons in that country. Many feel the weapons were to be used in a coup attempt in Equatorial Guinea, where nineteen were on trial for plotting. In addition to Mann, sixty-seven others involved were sentenced for violating immigration laws. 
During a review by the High Court in January, 2005, Mann's sentence was reduced by three years.
