Stevens had Bangura arrested in 1970 and charged with conspiracy and treason. He was found guilty and sentenced to death, despite the fact that it was Bangura whose actions led to Stevens return to power. Brigadier Lansana and Hinga Norman, the main army officers involved in the first coup (1967), were unceremoniously dismissed from the armed forces and made to serve time in prison. Norman was a guard to Governor-general Sir Henry Lightfoot-Boston. Lansana was later tried and found guilty of treason, and sentenced to death in 1975.
