He was a long-time aide to President Blaise Compaore, serving as commander of the Regiment of Presidential Security (RSP) during Compaore"s rule. He was appointed as chairman of the junta on 17 September 2015. Diendéré is suspected of having been directly involved in the 1987 coup that resulted in the death of Thomas Sankara and installed Blaise Compaoré in power.
Diendéré was commander of the national commando training center in Pô at the time of the coup, and all known assailants who were identified by the sole survivor of the assault, Alouna Traoré, as having served directly under Diendéré.
In late 2014, following the ouster of President Compaore, Diendéré was dismissed from his military leadership posts by the transitional authorities. Although he no longer headed the RSP, he remained closely linked to it during the events of 2015, in which the RSP found itself at odds with the transitional authorities, which wanted to disband lieutenant
On 17 September, Diendéré was appointed as Chairman of the National Council for Democracy, the new military junta. However, the junta failed to consolidate its authority across the country and faced pressure from regional leaders, and eventually from the regular army.
On September 22 the RSP agreed to a deal with the regular military requiring that all RSP troops return to their base.
On September 23 interim President Kafando was restored to office. Diendéré admitted that the coup was a "waste of time and resources.. and human lives were lost". A meeting between Diendéré and several West African leaders occurred after a ceremony celebrating Kafando"s return.
The government dissolved the RSP on 25 September 2015, and on 26 September it froze the assets of Diendéré and others associated with the coup.
After the army assaulted and captured the RSP"s base, Diendéré fled to the Vatican embassy. The government assured the Vatican that Diendéré would not be killed, and he was turned over and taken into custody by the government on 1 October, escorted by former President Jean-Baptiste Ouédraogo.
In addition to facing prosecution for the coup, Diendéré was also charged with involvement in Sankara"s death.
