 On 11 June 1975 several military officers were arrested in what became known as the coup monté et manqué . Amongst those arrested were Générals Daniel KATSUVA wa Katsuvira , Land Forces Chief of Staff , UTSHUDI Wembolenga , Commandant of the 2nd Military Region at Kalemie ; FALLU Sumbu , Military Attaché of Zaïre in Washington , Colonel MUDIAYI wa Mudiayi , the military attaché of Zaïre in Paris , the military attache in Brussels , a paracommando battalion commander , and several others . The regime alleged these officers and others ( including Mobutu 's civil secrétaire particulier ) had plotted the assassination of Mobutu , high treason , and disclosure of military secrets , among other offences . The alleged coup was investigated by a revolutionary commission headed by Boyenge Mosambay Singa , at that time head of the Gendarmerie . Writing in 1988 , Michael Schatzberg said the full details of the coup had yet to emerge .
