A coup attempt against Jammeh was reported to have been thwarted on 21 March 2006; Jammeh, who was in Mauritania at the time, quickly returned home. Army chief of staff Col. Ndure Cham, the alleged leader of the plot, reportedly fled to neighbouring Senegal, while other alleged conspirators were arrested and were put on trial for treason. In April 2007, ten former officers accused of involvement were convicted and given prison sentences; four of them were sentenced to life in prison.
