Boakye-Djan formed the Free Africa Movement with some colleagues in the early 1970s and they were planning to take power in the 1980s as senior officers in the army. Their planning was still at an early stage and the 15 May 1979 abortive coup attempt by Flight Lieutenant Rawlings forced them into initiating theirs as some of them were being arrested on suspicion of plotting against the military government. It appears it was one of his members, Peter Tasiri who actually initiated the coup on the day. There appeared to be a lot of confusion and no clear leadership during the coup events. In 2003 he said that the main purpose was to save Rawlings, who was facing a possible death sentence for planning a coup in the previous month. During an interview in 2017, he stated that he and Rawlings had grown apart and had not spoken to each other since the end of the AFRC rule.
